03/04 Ford Cobra motor
 

Would this fit? I'm asking since the blower is on top of the motor since it's a roots style blower so just an Idea other then going with a Ls1.. I've been thinking about selling my 03 cobra and doing this project...

Hmm wow that sure would be quite and undertaking. I dont know of anyone who has done this yet so you would be traveling on new ground for sure.

FC or FD?

Won't clear the hood, for sure. Strut towers and exhaust is a close fit. Non S/C DOHC motors have been done in FCs before. Rage was the member.

i dunno if you realize how heavy the 4v mod motors are, they are over 700lbs... plus they are wider then a bbf 460 cos of the heads
