anyone care to guess the numbers....?View attachment 30951 View attachment 30952
OK, based on my limited details of your build. all I know is that it's a 502, 10:1 CR, 75CC heads, custom grind cam (specs unknown to me) and a smaller single plane intake (I assume pump gas setup based on these). I assume with all the work into this and that you seem to know what you are doing, that the heads have a decent port job and that the intake is port matched. The big outstanding question is carb choice and jetting and header size. But, all that said here is my "guess"...
685 - 690 HP close to 6K RPMs (+/- 3% or 20HP based on altitude/correction factor)
605 - 615 LB/FT in the 4800 RPM range (I think it will be limited by the intake)
Yes but I don't know how to upload them hereVideos???

I wish! but I am pretty happy with what it did700.
Around here they are all 4x4 trucks with only half a lift kit (in the front) and glasspacks on 1" pipes so they make a horrid sound!I will go with 200 ponies less than every single one of the Honda nitrous injected, turbocharged street racers gathered over in the local Walmart parking lot. Had you done it right and invested in VTech you might have been able to keep up.
lol, Thanks Larry!I know, I know!
But you tell them.

thanks son, when I drive it out for the grand opening of Bill's Speed Shop I will let you drive it again!That is a beast. I’ve drove the car before and it had torque to spare. This whole combo will make this a completely different machine.
Good job.

oh by the way, the avg VE was 107.9, min was 104.3 and max was 110.2 according the the dyno data. That's pretty good for an N/A engine! I understand some DOHC 4 valve N/A engines can reach as much as 130% but I am pretty happy with this result. Usually over 100% is from forced induction. He said on the pull that we got that data he ran it up slower because it's more accurate....With your heads, cam and valvetrain your engine is likely pushing into the 90s on VE ...
