Any motorheads know about blown engines?

First post on the asylum but I would have a chat with the lightning guys as they use the bells in that CC motor all the time.

My last boosted project was a 65 cobra with a chevy 350 a 142 blower. Compression was around 9.2 and running about 9 psi with the street pulley. Better equivlent heads and a much more aggresive cam though.

Fuel is going to be your main concern as well as boost bleed off on the street. Cooling in a mustang with that motor and clearance on the top is going to be a issue as well, a extended cowl and a dual fan setup with some careful coolant choices (with a larger radiator) is going to be a must. I had major trouble getting everything to fit in my 67 K code and ended up hack then bar up a good bit out of the front of the car.
