Ai 220 / 230 - .560" / .555" - 112 LSA
Our version of a GM LT4 Hot Cam, but with the potential to make another few hp over the old GM grind. Typically makes peak power at 5800-6000rpm in stock LT1 long blocks. Properly tuned this small grind will run and drive well with stock gearing & converter.
Ai 226 / 234 - .566" / .566" - 110 LSA
Easily our most popular daily drivable grind for 350cid applications. Typically makes peak power at 6000-6200rpm in stock LT1 long blocks. Properly tuned it will run and drive well in M6 cars w/ stock gearing. A4 cars should run a 3.42+ rear end gear & 2400 rpm converter minimum. Can pass emissions in some states on 110° LSA, though 112-114° LSA makes it more likely to pass.
Either one of these would do well.The first one would be a better choice most of the time unless you have done other modifications.Make sure you change the valve springs and it would be a good time for a roller rocker upgrade.You will need to have the computer tuned as well.I am sure you already know this but posted it just in case you don't.

Nice
my car has the hot cam package with springs and higher rocker ratio, the power range is good. But i'm not comfortable with the idle. I wish it was little smoother.
Am doing the same. I had the hotcakes on another build (imp ss lt1) ND am going with the cc503 or gm846; both are about the same spec and higher yield over hotcam.
