Trick flow heads how are they ?
With the new information on the old cam lift then again we don't know the duration...
If you was running 12-3 I would say he's got 11 8 or 11 7 licked... But with no other changes except the heads and cam I think 11 3 is a bit of a stretch but that's just one extremely slow stroker guy's opinion... (AKA.. the slowest stroker on the Forum)...
