When I tear the front off I wanted to have what I needed to put it back together after degree-ing it in. MP offers a offset key package.. can be bought from Mancini's.... just in case you need more... see where it is now but I would move it more.. even if its slightly advanced now.. just check the V to P clearance EDIT I have moved a 108 lsa cam as far as 98* installed but that killed my top end RPM... I had to back it up to 101-102.. but at 98 it sure did have a bottom end (torque) Last edited by MR_P_BODY; 03/18/15 02:07 PM.

He likes the feel of the power...problem is where its at he's already speeding before he gets to feel it. I'd like it to hit a lot harder and am willing to sacrifice some top end to get there. Sounds like it needs advanced beyond recommended... ...FAFO...

HotRod did a torque convertor test years ago and it was suprising how well the highway gears would do with a good convertor. I think member Big Squeeze has a story where with a good convertor he was able to run very good times with 2.94 gears compared to a 4 something gear in the same car IIRC
