Under the hood
in any '94-96 Roadmaster
you'll find a LT1 5.7 Liter V8.
Factory rated at 260 hp
and 335 ft lbs torque.
The F-Bodys are rated
higher (275/335). Here's why:
There are four basic differences
between the LT1 in the B and F bodys:
1) F-Bodys have cast aluminum heads.
B-Bodys are cast iron.
2) The compression ratio on the
F-Bodys is 10.5:1, and the B-Bodys is 10:1.
3) Camshafts and Programming are different,
as the B-Bodys weigh about
650 pounds more than the F-Bodys.
4) Exhaust systems are different.
The stock F-Body exhaust is less
restrictive than the stock B-Body exhaust.
For lots more current engine pics,
especially modifications,
please see page 9.

I keep my LT1 happy with
Castrol Syntec Oil,
meticulous maintenance,
& quality parts.
On any given day,
you could eat off of my engine,
it's always really clean.
What my engine looked like when I bought the car.
This is AFTER I cleaned it up.
My engine isn't stock anymore.
Stock 48mm TB on the left. 52mm BBK TB on the right.
Look at the built in air foil on the BBK.
The BBK is not only larger, the inlet is smoother.
Why did GM design the stock TB this way?
This is no way to flow air!
Speaking of air flow....
I have a 3.5" F-Body MAF,
with Granatelli Ported
Composite MAF housing.
No screen.
Better air-flow,
and because it's made
of composite material,
there is no heat soak.
The stock B-Body MAF is 3".
Since were on the topic of air flow...
My Ram Air System is a
huge improvement over
the stock intake system.
I've made a few
modifications to the RAISS.
The red covers are
made by Outerwears.
These are water repellant pre-filters.
This is the original RAISS setup...
This is before I had the RAISS...
This was my very first mod:
Scorpion Roller Rockers #1036
1.6 Ratio Self Aligning
Scorpion Roller Rockers for small-block Chevrolet LT1/LT4 applications.
Rocker ratio is 1.6, and fits standard 3/8" rocker studs.
Excellent replacement for OEM stamped rockers,
and mandatory for high-RPM operation.
High quality extruded aluminum construction and
100% MADE IN THE USA.
CNC Machined high strength aluminum
Stronger than Crane Gold and designed for more valve spring clearance
Will work on up to 1.550" OD valvesprings and retainers
Needle Bearing Fulcrum and Roller Tip
Centerless Ground Trunnion, Pin & Roller
Thick walled poly locks machined from solid steel and black oxide coated
Built to withstand up to 800 lbs of valve spring pressure and .800" cam lift
Scorpion roller rockers are also clearanced behind the roller pin
for increased valvespring retainer clearance over other brands.
Take a look at the photo below for comparison:
GM LS2 / LS6 Beehive Valve Springs
part #12586484.
Comp Cams 787 Retainers.
I wanted to upgrade the valvetrain on my LT1,
and not break the bank.
The Scorpion 1.6 ratio Roller Rockers
are a quality product,
and are made in the USA!
The LS2 / LS6 Beehive Valve Springs
will be a big upgrade from stock,
and will work well with the 1.6 Roller Rockers
and the stock camshaft.
Comp Cams 787 Retainers, Stock Locks,
and Fel Pro Valve Stem Seals
complete the valve train upgrade.
I have Bryan Herter PCM programming
(pcmsforless.com).
Bryan is one of the best .
Bryan has finely tuned the brain of my Buick,
and in the process created a Road Monster!!!
I've been focusing on the Body,
Interior, and Gran Sport Theme .
The Transmission was rebuilt,
the complete suspension &
brake systems were rebuilt
& upgraded.
With all of that finished,
I can start the really good
performance modifications!!!

No More Mobil 1
I used to use Mobil 1 5W30 Synthetic.
I don't anymore.
I have since learned about oil,
& found out that German made
Castrol Syntec 0W30
is the best oil for the LT1.
The "red label" Castrol made in Germany.
Good Stuff.
