The 218/224 I have now is mild and its not a problem getting it moving even with the stock converter right now. It really comes on power at 2500 to 5000. What you think about the 224/230 on a 112lsa.

I believe it to have about 4 degrees built in if I have the camshaft info right using the camshaft overlap, etc formulas.

Dyno Desktop shows the 230/236 on a 113lsa to peak around 5800 and the 224/230 on a 112lsa around 5500.

Yes,a lot of the Comp. cams have the 4 degree's advance built in to them.
Don't forget the timing chain will stetch the four degree's and maybe more.

Yea got ya, I'll be using a double roller with billet/steel gears. We can finish this through PMs if that's cool so we don't have to go back and forth so much.
