It should have great street manners. You should be able to outrun a stock vette, I don't know about crushing one. Vettes are fast! BMWs no problem. I say stay small. Maybe 2600 converter if you want one bigger than stock. I wouldn't go too big, traction issues.

 

Mag was on board with the head specs. They say I cuc run the Mp112 on these if I ramped up boost to 11-12psi, but above that heat becomes too big a prob. The Mp122 shud be more than enuf to handle this they say...if not, I guess we'll change 'em up!

 

Already cut and delivered, but I'm gonna experiment with at least one other so just trying to decide what that'll be. R/

 

On a 370 the MP112 would never achieve 11-12psi without being overspun to the point that it would only make good power in short bursts and that problem would only be worse with heads and cam. I am interested in seeing if the MP122 can do it on a well built setup like that. I am assuming it can also.

 

Its the setup that Maggie and BlownChev seem to like....500+rwhp shud be easily achieveable - I hope
