Hey guys,
I have an L76 block with 799 heads.
I'm trying to calculate compression ratio & pick up a good cam for the set up.

Bore size = 4"
Piston Stroke = 3.62204724"
Head Gasket Bore Diameter = 4.08
Compressed Head Gasket Thickness = .051
Combustion Chamber Volume In CCs = 64cc
Piston Dome Volume In CCs = -2cc valve reliefs
10.24? sound right?


D1SC is 4.53" Pulley IIRC.
OEM C6 Balancer
1 7/8" to 3" LT Headers reduced to 2.5" X pipe back, catless.
Ported LS2 intake
92MM TB
80lb injectors

I was considering the Jam Cam since its been claimed to be easy on the valve train but something about the lope has never made me feel committed.

Here are some I've come across
-Speed Inc. SC1 cam
222/228 .566/.571 114LSA.
"Lower lift for valvetrain reliability, low overlap for less wasted boost."

-EPP Blower cam
232/240 .595/.609 115lsa

-Tick LS2 STG 2 Blower Cam
231/247 | .63x"/.63x" | LSA116+5

-Comp CAM 54-477-11
227/243 .614/.624 114LSA


The car is roughly 3200lbs and has no traction control. Goes nowhere in first from a dig with the 3.9s. This makes me want more top end then low end. It's also aimed to be a daily driver, so I'm perfectly fine with the stock cam. However, the motor is apart and currently had the DOD cam in it. I purchased an LS1 cam for 50$ but I think it's optimal to change the cam to match my cars purpose.

Fuel economy would be nice - but not expected. Hell, better then the rotary that was in it before even if its swallowing bricks.

Thanks in advanced guys!

10.24 seems on the low side but the calculator I used does not take into account head gasket bore diameter.

Our blower cam has proven itself over the years to make a huge power increase when used with forced induction. I would not hesitate to use it with your combination, you would be impressed with it. Bob
