What’s the least LSA anybody has run with stock heads and short block before facing ptv clearance issues. I want to get a cam with 108-110 LSA and with 2-4 degree advance on the stock heads and short block that I have, this is for a 99 Z28 A4 with full bolt ons.

 

as long as the lift isn't insane, the 110 should be fine.

somebody had a 110 cam in their lineup...maybe futral...can't remember.

 

i'm running a 110, the only thing I recommend is a DAM good tuner.

 

If you want a big stupid cam like that, I suggest the F-15 from Futral Motorsports or the T-rex from Thunder Racing. They are both 110 LSA cams.

Isn't the ASA cam a 108?

**nm it's 110

 

there is more to consider than LSA, duration plays a huge part in PTV, I run a 232/240 .579/.579 110LSA cam with stage 2 heads with no PTV issues and no flycutting.

 

I don't want to have a huge cam, just one that maintains a good DCR and with good overlap to help the stock unported heads breath better. Maybe something like a 232/234 on a 110 LSA and 106 ICL would be good.
