Well,  I finally finished putting together a "Fully Forged" 388ci Bottom-End.... All of the Engine parts were Selected & Blueprinted with a lot of the focus being it's ability to reliably handle "Quite a Bit" more nitrous than I was previously spraying on the stock lower-end (Most of the time I pretty much stuck with 125-135 RWHP shots on the stock lower-end (which was always 100% trouble-free at those settings since putting the first nitrous kit on the car back in August of 1998, if you can imagine that.. LOL).... The new forged Bottom-End is set-up to handle 200 + RWHP shots...... THE NEW BOTTOM-END PARTS LIST & MACHINE WORK ARE AS FOLLOWS:.... BRAND NEW (Lucky Find) LT-X Iron Block....

ATI(SFI) Approved Neutral Balance Flexplate......................TRACK TIMES WITH THE "NEW" COMBO: Some more track times with the newest engine, and nitrous set-up, will be posted pretty soon.... MOST RECENT TRACK DAY  FEB/2009: After running a bunch of Naturally Aspirated passes (and always letting off just after the 1/8th mile marker, as to not get kicked out right away), I made one final pass for the day with the newest Engine & Nitrous system set-up.... With a few gallons of some Rocket Brand 118 Octane dumped into the few gallons of 93 octane pump gas that was already in the tank.... I sprayed a 225 RWHP shot (which I previously had tuned in pretty good on the street).... Spinning in first gear a bit too much, (Yielding a "nothing special" 1.58 60 FT time) It still went right into the high 9's on the very first pass, at over 137 MPH.... and just as quickly... before I even got back to the pits, I was greeted by a "overly smiling" track tech, and red-flagged for the day, LOL..... (As of March '09) I'm still in the process of finding some free time (and some extra cash ,LOL) to get a nicely done regulation (8.50 Index Rating) molly cage in the car so that I can really tune things in right (and as safely as possible).... At that point, I would imagine that the car really needs a few good test & tune days under it's belt to try out some different shock settings and such.......Thanks a lot for looking , and rating my car......... Joe  ..........PS: Any questions, about set-up or anything.... don't hesitate to ask.... I've been building engines , and setting up street/strip cars like this for "well over" 20 years now (since I was 16), and I'm always happy to help out other car guys, or point them in the right direction since there's a tremendous amount of MIS-information out there ,"especially" on the Internet forums.

ROCKER GEOMETRY & PUSHROD LENGTH CHECKING METHOD: "Click">>>>>Link text

ROCKER GEOMETRY CONT:.... "ALWAYS" (With the correct method) Check your rocker geometry to find out "EXACTLY" what pushrod length your particular engine combo needs to attain the "correct" rocker geometry. (Never just throw your stock length pushrods in there, or take someones word for it on the legnth that you'll need for a particular engine combo).... Many variables such as Headgasket thickness, Clinder Head deck thickness, Engine Block deck height, Head surfacing, Rocker Brand & Design, Lifter Design, Valve stem length, Cam base circle size....Ect....Ect....Ect.... can ("and will") affect your rocker geometry, and your engines required pushrod length.... Also, don't skimp on a set of pushrods for your engine (Buy the best you can afford) The Comp-Cam "HI-TECH'S" are a good, "and still affordable" choice."Click" >>>>Link text

LIFTER PRE-LOAD SETTINGS:.......We'll, After "ALOT" of experimenting with just about "every" possible lifter pre-load setting on earth trying to attain the best possible performance at the track (Examples of trials: 1 full turn preload after zero lash.... 3/4's turn preload after zero lash.... 1/2 turn preload after zero lash....1/4 turn preload after zero lash.... 1/8th turn preload after zero lash)...... I have "definitely" found that setting them "ALL" at true ZERO lash , and then setting the polly lock normally ,(which takes about 1/16th of a turn to lock), yields the best dyno "and" track numbers..... So "once again" the best setting for this engine combo is setting them at 1/16th of a turn preload "AFTER" true zero lash (yup, it's not very much at all... and yes, it's safe to do.).....I have also found this setting to work best on nearly every LT-X / LS-X hydraulic roller cam set-up(IE:Dozens and Dozens)......For those unaware... OEM style "HEAVY" Hydraulic roller lifters have a STRONG tendency to bleed down at high rpm... This happens to a large degree because of their excessive weight, and the "increased" valve spring pressure's that come along with using "larger than stock" camshafts (and the lifters also get worse with age, of-course).... And not only that, but "Some" Hydraulic lifters also have a tendency to "pump up" at higher rpm's causing your valves not to be seated when they should be during their open/close cycle.... This (if bad enough) can cause an absolute "HUGE" power loss.....Initially, my engine combo had "BOTH" of these issues going on (many others do as well, but just don't know it).... Many guys just think that there car doesn't pull very well on the top end of the RPM scale....... After a switch from my regular Mobil 1 5W-30 weight oil, to "Heavier" Mobil 1 15W-50 weight oil (which will help "ANY" hydraulic style lifter from collapsing as easy at high RPM) and setting my valves with the 1/16 pre-load previously mentioned....It was like a night and day difference from 5500 RPM's up to my 6600 RPM shift point....Before these changes, It used to really fizzle out after 6000 RPM's... Now it pulls REALLY HARD without ANY signs of waining up to my set shiftpoint, and has picked up 36 RWHP on the dyno at peak RPM.... This kind of hydraulic lifter "finicky crap" is why many out there (including myself) switch to a solid roller type set-up.... A set of the "High Dollar" Morel hydraulic roller lifters, or the NEW GM Lightweight(Ceramic Internal) Hydraulic Roller lifters that were recently developed for the Cadillac race team will correct most "if not all" of these issues (After all, this is why they were developed), but IMO, and experiences... The hydraulic stuff is "nearly always" problematic in a High-RPM, High-Performance application , and in one way or another it's usually cutting some power off somewhere in the RPM range compared to a similar spec'd solid set-up.... Just my 2 cents.(we'll maybe 3 cents, LOL).

Cam Degreeing: "Click">>>>>Link text... IMO, Doing this "in car" (on a Corvette) isn't very fun at all.... but the alternative is not having a single clue where your Cams recommended (IE: intended by design) installed centerline is.... And on these cars, it's even more important than most.... For every degree your cam timing is off.... your Opti-Spark controlled ignition timing will be off "DOUBLE".... Now consider the common occurrence of degreeing the cam , and it being off somewhere between 3 - 7 Degree's, (or even more), it's much more common that you can imagine.... yup, not only an engine with horrible cam timing, but also an engine with ignition timing that's retarded or advanced 14 degree's (or even more).... Think it'll ever run good, LOL.... It's stuff like this that's responsible for many a crappy running car out there.... Cars that, "for their mods" run nowhere near how they should (we "ALL" know cars like these).

OPTI-SPARK DISTRIBUTOR TIP'S:  If your doing a factory type optispark on your car... NEVER,  JUST SLAP IT ON... spend the extra few minutes and remove the cap and the rotor inside... Clean the rotor bolt threads (BOTH the male and female threads) with some Aerosol type brake parts cleaner or something similar to get ALL of the oil off... Then RED (High-Strength) loctite your two rotor bolts back in place.... then take a tube of silicone RTV (IE: Permatex sensor safe silicone RTV works good) and run a nice bead sealing "EVERY" possible seam where the Opti-spark unit comes together.... Don't trust the Opti-Sparks internal gaskets to do this adequately enough for the life of the unit.... ALSO, seal very thoroughly with the Silicone RTV around the electrical harness plug "on the top of the Optispark unit" right after you plug it in..... I know these PRE-installation suggestions here seem simple enough, but honestly... 90% of "ALL" the PRE-mature problem issues associated with the Opti-spark units are from when the rotors very commonly vibrate loose (tearing up the inside of the unit)... and/or when water gains entry inside of the unit (this happens "very easily" if their not sealed really well)..... I've been sealing Opti's like this on LT-1's & LT-4's for over a decade now, and have yet to have a premature issue with any of them......Also, something I feel worth mentioning to the LT-X guys out there (Like Myself).... at this point in time (Dec 2008), I would still resist the urge to drop $500 plus dollars on the MSD Opti-spark unit...As nice as they look, MANY are still absolutely riddled with problems...Just, as is the case with many "Newer" products released, they just don't have all of the bugs out of them yet.... I can't even tell you how many of these "flat out failed" and/or failing" MSD Opti's I've pulled out of peoples cars for them, only to switch them back to a Genuine AC/Delco Opti-spark unit (prepped as mentioned earlier) without a single future issue.

RAM-AIR INTAKE SYSTEM: Breathless Performance Vortex Ram-Air Intake Installation Pictures......As far as Cold Air Induction Kits go for these Vette's, I've pretty much tried them ALL over the years since this car was new (BOTH at the dragstrip "and" the Dyno)....I'm not gonna name actual brand names of which ones aren't worth a crap,lol.....But I will say for a proven "trial & errored" FACT.... That "UNLESS" the cold air intake system is of a design  (Similar to this Breathless Performance system)  that receives cool... constant... pressurized air from "OUTSIDE" of the vehicle  (IE: "OUTSIDE" of the HOT engine compartment)  then don't even consider wasting your hard earned money on it .....Some of the common "and expensive" systems out there for the C4 Corvettes look pretty with their cute little "tripple" style filters, but in actuality, they suck the "same exact" stagnant hot air as the lousy factory unit does (and in the "same exact" horrible "Blocked-In" location)...and even worse, some are even made out of thick metal, which (after driving for a while) retains heat on these cars like no tomorrow, and actually passes "some" of it on to the passing air flow  (This is just the "exact opposite" of what any good CAI, or Ram-Air intake system should be made out of, or doing).... So the long and short of it is... if your gonna have a system that exhibits it's effect in those VERY undesirable ways (which litterally 99% of them available for these cars do) , you'd honestly be MUCH better off saving your money, and simply sticking with the stock ABS plastic set-up, putting a K&N air-filter in it, and trimming the top of the louvered factory metal Air cleaner lid off yourself with some tin snips or a dremel tool with a cutoff disk on it (IE: the commonly performed "cut-lid" mod).

A few shots from "under" the front clip of the car.

This Ram-Air kit, combined with using "solid" (NON-accordian type) air intake coupler tubes , like I'm using on my car (reguardless of making adjustments), has a tendency to not give you a "perfect" air-tight seal where the cone filter's base seals against the clear air-box itself (Because of engine torque, (IE: movement) pulling on the filter in relation to the "fixed position" clear air-box).... So take some high quality adhesive backed soft rubber weatherstripping and seal this area. (which was later done "after" these pictures were taken).
