To sum this all up. The only dynos that I know of with AFM cams:
1) Superchevy and the got 63 WHP with largest comp AFM cam and air filter
2) Ligenfelter with a much smaller cam claims 550 engine with heads, filter, tune say 475 wheel. GT30 cam... smooth idle
3) KingLT said same package with LT put out 503 to the wheels.

It looks like TSp no longer markets theirs... red flag to my mind

General wisdom is pull the heads.. you should port them while they are out. Run good lifters, it is hard to overcam these cars and you should probably look at a minimum 22x duration. Also everything has to be spec performance, springs, retainer, pushrods, trunion. From me and GM, for FI, on LT1 the valves are suspect you need Manley ProFlows. Only with a real cam and ported heads are you going to see gains NA.

What I'd like to see is a AFM cam say 224 / 234 120 LSA 550 lift 35 percent fuel lobe made as a mild FI upgrade for stock LT4 or for LT1 with FI.

I'd like to see a full bolt-on AFM cam dyno with ported IM,TB and E85.
