bring it!

sounds good though man! your not goin to chuck a blower on anymore? or you'll do that later on when you've got some more money? bloody expensive to do it all in one hit i know, too rich for most.
see how you like the n/a stroker first then decide, i know im content with the power and torque ive got for a daily driver.

I'll chuck on the supercharger when I replace the trans, tail shaft and diff.
Somehow I don't think they would handle the power with a SC on top :)

yeah, they would struggle to handle the torque that it would be pumping out. what kinda s/c are you thinkin of and how much boost do you wanna run? important to think of that before you built the engine, so you use the appropriate cam, pistons, compression etc..

wiseco or keith black forged pistons would be the go, with around a 8.5:1 compression depending on how much boost you wanna run when you get the s/c.
that cam would be alright, its not all that big though, if your porting your heads you can go bigger than that. im curious as to why you want a crow cam? you dont wanna c.o.m.e. cam?

Are Crow Cams not as good as COME ones?
well at the risk of being flamed here....no. there's nothing wrong with a crow cam, but c.o.m.e. do offer a more "individual" selection to suit what your application is and they have a variety of cams to complement the stroker.
