"Guys two of us here that have had first hand experience say lets get it back to his question and stay with IA blocks. No cheerleading either!
Aftermarket blocks are a new deal for alot of us in the Pontiac community-old hat for many Chevy guys. There is a little learning curve but a good machinist can help figure them out."
Maurice look back a few posts to this-no jabs at KRE trying to get it back on track and suddenly we get it off track in both directions.
So yes when we get a "cheerleading tangent" especially one saying there must be another side I'm going to bring up some points I have experienced and can document. And I am probably one of a fairly small "club" of folks that have had an MR-1 and an IA2 ,maybe not to the power level some of the other folks here have , but that isn't my goal a dependable 700+ HP.So issues with both "normal" and abnormal I have experienced
I can also tell you some potential issues with some of the new aluminum 409 heads I'm going to have to resolve, but that's a whole new tangent.
