My Road Trip Motor Progress
Joel Mohr:
I looked at the dyno sheet Bill, and the timing is at 30*...With Dougs new muffler, I would bet that motor made close to 200...yet drives like a stocker...and the 48 idf carbs are off the shelf... with some carb work, i would estimate 210...through the muffler, belt on. 8)

Johl,
I heard Gene mention when he was still with us that he would put a lot more lead in the timing that 30 degrees. Of course, cam combination/overlap and everything else come into play.

Joel Mohr:
When I worked for Gene, he said max compression WITH a hemi cut was 7.8 to 1...He recommended 7.5 as a max for stock chambers. With the extra static compression, timing will be moved to accommodate the flame travel of a tighter squeeze.

Beautiful! Those look exactly like my street car heads,(but I've got 46x36 valves) I'm running 11.2 to 1 without any problems at all...2442, cam is a special grind, .650 x 310*... makes 215 with the belt on through the muffler...
what type of heads-vw or aftermarket? can that valve combo be used in a modified vw head?

My heads started life as 041s...
