Considering Going Modular

I have a buddy that has a 03 mach, comp cams, stock long block with longtubes and a ported shortrunner manifold (stock casting). He is in the 375rwhp range. The thing pulls to 7200 so strong. It is a great car. He has 4.56's as well.

I don't have a 4 valve but from what I have seen, there are a variety of cams. There aren't any aftermarket heads that I have seen but people get theirs ported, polished, and what not.

The old heads, cam and intake route is expensive on any modular motor and the gains are not as great as you get with boost. Mod motors love boost. The rods are the weak point in our motors, so there are limits with the boost before you have to forge the bottom end.

That being said, I don't think you would have any issues building any naturally aspirated setup on the stock bottom end.

Machs are my favorite of all the SN95s. They don't disappoint, even in stock form, not to mention looking bada$$.

There are crower and comp cams. Also the heads on the mach1 and cobras flow very very good there is no need to port or mess with the heads unless your pushing 1,000+ rwhp. Also the mach 1 is same as the cobra except there is no eaton supercharger. There is a sports car dealership that is in my area that sells the most 03-04 cobras in the world they have LOTS of parts sitting around. if you get a mach 1 you could get an eaton blower from an 03-04 cobra that is a direct fit. hi-endauto.com is the website.
