Didn't you have some off brand intakes? If so are there any dyno proven setups using the same intakes?

741 cam is hard to beat.
have you and your buddy scaled your boats?your's may be just that much heavier than his.

The 502's that you referenced also had marine kinetics cams.
The engines have Edelbrock heads and dale cubic 750cfm carbs.

To be fair, those numbers were with only a water pump and dyno headers and on a different dyno.

Remember, Full Force has lower compression. What was the exact # FF ?

I was wondering about that. It would make sense if he was down under 9 to 1

9.5:1 and compression tests 165 average

Was it ever cc'd?

One shelf grind is not going to be ideal for every combination. The closer the cam is to being "ideal" for a given combination, the more power it's going to make within that cam's design limitations. That's why some combinations with the same displacement will make more power than others, given the same cam. There are lots of other factors in an engine build that contribute to making power, so that needs to be taken into consideration as well. You can't just assume it's the cam when comparing different builds by different builders. Don't get too caught up in that.

Assuming 6000 propped max rpm

650/620
243/253 .050
112 LSA

Lunati never made their pistons, they were always subcontracted out and I believe Weisco had the contract the entire time. Comp Performance Group bought Lunati around '03, '04. Comp Performance Group bought Crane 2 years ago this month.
