Transported 460, 500hp/550lb.ft. Big improvement over the 400 which had about 165hp/300lb.ft(next pic down). I did run the first 400 for about 6 months(although dressed up a bit, see pic at bottom w/blue valve covers). This engine would not cooperate however and would run on about 5psi of oil pressure at idle, so out it came for another 400 shortblock until the battery managed to fall(always use a battery hold down guys) into the flex fan and sent it into the radiator, poking a hole(actually several) in it and puking out all my coolant. Without coolant your engine will not run very long, and for me this was about 10 minutes at about 50mph before I knew I had a problem. By then the temp guage was pegged past 280 and the truck stopped on it's own, I had cracked a head and blown both head gaskets. So, enough with the slow, oil-leaking, gas guzzling 400's, in went the real Big Block! Long list of engine mods includes: 1979 D9TE-AB truck block bored .030" over to make this a 466ci beast. Block was also align-honed, torqueplate-bored and had all new freezeplugs/gaskets/seals and Clevite 77 bearings put in. Crank and rods are stock truck pieces, but pistons are forged Speed Pro flattops that give about 10.8:1 compression with the 72cc heads. Cam is Lunati hyd.-.516"/.543"lift & 288/298 duration, has some lope to it but is really torqey and pulls to about 5500(can spin this motor about 6500rpm). Heads are DOVE-A, stock valves, ported/polished int&exh runners, double wound valve springs, Scorpion roller rockers, Comp Cams 3/8" hardened pushrods, Milodon guideplates, Ford Racing polished aluminum valvecovers. Intake maifold is a Weiand Stealth and carb is Holley 850 DP that had been flowed to 920cfm. Other goodies include: Weiand aluminum water pump, MSD 6A ignition/Blaster 2 coil, Ford Racing 9mm plug wires, electric fuel pump, electric fan, aux. oil & tranny coolers, Dual Optima Yellow top batteries, and a K&N 14"X4" aif filter w/ xtreme flow lid. This motor gets about 10mpg, but really doesn't like any thing less that AV gas(leaded, about 100octane), or Cam 2 unless I pull timing back out of it, but then it's a dog. All that is breathing through L&L nickel plated headers w/ 1 3/4 primaries/3" collectors open for track & Flowmaster 40 series/2 1/2 side exit for street.

The first C6 I had in here came in it from 1979. It still shifted OK for a 25 year old unit that had been beat on for all it's life and had been sitting for about 5 years, but eventually it had to go. That time came when I discovered a small puddle comming from under the center of my truck. Knowing it couldn't be my nice new fancy motor, I looked and discovered it was tranny fluid. Come to find out somehow(hmmm) I had managed to split the entire case of the transmission from the band adjustment on one side, to the pan rail on the other(pretty much from the tranny pan on one side, all the way across the top of the tranny, to the other pan rail. So, in went a ribben 2wd case will my 4wd tail and lots of go fast parts within.

Pictured below are some odds and ends shots of the chassis, undercarrige and the like. The stock transfercase remains(NP205 boltup), albeit with new seal/bearings/fluid. Moving down the new u-joints and balanced driveshafts, we come to the next add on: GM 14bolt 1 ton full floater rearend. This unit came from a 1985 GMC 3500 Dually truck, pretty much the largest unit you would want to put in a street driven truck where weight is a concern. Stuffed with 4.10 gears, detroit locker, DISC brakes, new bearings/seals/fluid, it would prove tuff enough to withstand a few years of relentless teenage beating, which is more that I could have said for the stock 9in. The front WAS for the longest time a 3/4 ton 8-lug Dana 44 fitted again w/ the 4.10's, true-trak locker, new Warn Premium lockout hubs, new barkes/bearings/seals/fluid and also would hold up fine considering what I did with it, only one broken ujoint came as a result of my punishment and it managed to leave the hard to find axle for the 8lug alone. Tires and wheels went from 36x16x15 Super Swampers/15x12 white steel wheels to 35x12.50x16.5 BFG All Terrains/16.5x10 white steel wheels to 36x13.50x16.5 Super Swamper Iroks/16.5x12 Mickey Thompson aluminum wheels, from older to newer. Those Iroks really pulled in the mud when spun by the big 460, but I don't think the 400 could have turned them, as it had a hard enough time with the All-Terrains in 4-low, where as the 460 would shift into 3rd gear spinning all 4 Irok's in 4-low, or I could really throw a rooster tail if I left it t-case in 2 high and ran up to 3rd gear in the tranny, spinning the tires to about 75mph!!! My buddy Justin can attest to this as I did manage to pepper him and his girlfriend(they were standing about 150ft behine me) at the mudhole one night.
