Don't take offense kingdragon but I would seriously think about a second opinion. My home ported Js hit [email protected] on a bench that is rumored to be on the stingy side. They peaked at [email protected]. The low peak was either due to my lack of porting ability or if the rumors about the bench are true then they are right where they should be. Im not gonna ship them to someone or take a day off from work to drive to the next nearest flow bench so the world may never know lol.

No offense taken here, trust me.
I'm well aware of the possibilities of the performance castings of yesteryear's. I ran a heavily worked over set of "U" castings on three combos for my car in years past. With each season I'd have them broke down and kissed just a little more. My initial reasoning for the direction of the Indys was the Iron and chamber. We went from a open chamber w/ a dome to the Indy chamber with super tight squish. In retrospect an W2 would of suited my package better, and most importantly allowed a higher window per-say for improvements in the future.
