On the intake I'd be running a Performer RPM and I have a Pro Systems 950.
I was hoping to be able to run D ports so I wouldn't have to swap headers but 3 different builders said those numbers were highly unlikely with D ports. IV's would give me the best option and yes, I'll have to find someone to do port work. Rules are internal engine mods are open.
I didn't know there was any difference between a 614 or 722 and with how hard they are to find I might have to take whichever. Given these will need everything new and be build specific, bare cores would be best.
I'd like to be around 11.5:1 or so, this engine has to live for long races. The bottom end is very solid and the cam I run performs well with the KRE's I have. Running solid rollers and 1.65 rockers for about .615 lift. I actually have a brand new cam I haven't installed yet, same specs but with a 4-7 swap.
Do the IV's come with the push rod hole already elongated?
