did you already buy the kit? If you did it should be fun, if not and you have more budget i would look into building a 408 to see what the price difference is vs gains.

You also might want to ditch that MAF and go SD as that will be a restriction on your intake side unless you can pony up a few more dollars and get a bigger one. If not it wint hold you back too much.

Depends if you can lock the converter on the dyno or not? In a m6 car I would think 480-510whp is possible depending in the cutouts are open and you take the time to set every little thing up right. Ported fast, tight quench, etc, etc. It's all in the details.

yes all the parts ordered or previously owned by me. so this will be how it goes together for now. I might buy 100MM Mafs later but not right now. So i was thinking between 430 and 460 tops don't think you can make 500 with these heads.
