I'll say more than 400 at the wheels. I think if you had the heads ported by someone better, you'd easily have 600 at the wheels. But hey, what do I know...?
Yeah, your a punk. lol. What do you know eh? haha. All joking aside, these W2's you have done are proven heads.
For a comparison, The engine that came out of the car was a 434ci. stock block 318 engine. At first, I was running my heavily worked over J heads with 2.05/1.60" valves. The compression was 11.5:1 and the cam was 262/262 @ .050" and .575"/.575" lift. (off the shelf comp)
We bolted Brian's W2's on the engine, which brought the compression up to 12.8:1 and changed nothing else in the engine. the lift was now around .650" with the 1.7 rockers. The car picked up 91rwhp just from the head swap.
HEADS ARE IMPORTANT. haha. It will be interesting to see what this combo does I think.
