Bored 60 over
Scat 9000 series 400 Block Crank
4340 forged Eagle H-Beams 6" Rod

Holly Dbl pmpbr 850 cfm

The pistons are 10.3 compression KP "Hyperpatethic" 0.60 Flattops


I am getting a custom roller cam made specific to my needs so i can keep a good powerband.

The lift will be 0.600 on the intake and 0.62 on exhaust

The question i have is will I have enough clearance with that size of cam lobe?

And how can i check?

put some clay/puddy on the piston and turn the motor over by hand after torquing down the head. Measure the distance at the thinnest spot of the puddy.

 

you need to dummy it up and check, my guess is you have pleanty of room, but you need to check to know for sure

 

I'd be more concerned with cam to rod clearance. Might need a small base circle cam.

 

Thanks for all your answers

and thanks katman for mentioning cam to rod clearance... i wouldve never thought about that.

After a bit of reasearch i will require a 1.786” nominal journal diameter, so ill really have to get that custom grind cam

Thanks!
