In advance I'd like to say thanks for the help...


So I'm wondering if this setup will work on a ls1 it is a Callie's compstar crank 3.622 stroke with compstar 6.125 rods and mahle pistons with +4cc flat top ch 1.340 will this setup work with either a 61cc or 65cc head don't want to bend my valves due to not enough clearance.

 

Could really use some help guys!

 

Check, we can't tell you online..

Research how to check piston to valve contact...

Since you have a domed piston I would never estimate. That must be checked out in person

Don't let predator-z see this post... He will let you have it!! Lol jk

Just check, it's the same concept as measuring pushrod length.. There should be no guessing in building an engine, you either do it right or it breaks...

 

I wouldn't pay for a Compstar 3.622" stroke. GM is more than adequate and is cheaper (especially if you already have an LS1).

The +4cc is a reverse dome with reliefs, I believe. Still, you'll need to check PtV...

 

Chances are you'll have way more than enough clearance with the valve reliefs, but you didn't even mention cam specs so no one will be able to answer.
