new LS1 build
Hello LS1 world.
I know it is always good to check valve to piston clearance for bigger cam installs but was curious if anyone has installed the new Comp Cam Thumpr cams in their LS1 yet?
I have the ***** Thumr with specs:
.564 intake
.547 exhaust
total duration is 283 intake and 303 exhaust
The catching point is the lobe separation of 109
Lift is not a big issue it is the lobe sep that makes me worry a little bit.
I have new Dart Pro 1 heads and new Mahle forged pistons that already
have valve reliefs in them .. gasket is Felpro .053"
Thanks for anybody that can give some insight.
