You might be surprised how much fun they are. I remember shifting to third at 60 or so and chirping the tires big time. They are quite a bit quicker than a stock 80s Mustang GT. I got about 35 mpg on long highway trips, too. The modern 5.0 is more fun, though.It's not going to weigh that much less than other alternatives -- aluminum head 5.0L, or all-aluminum LSx motors from GM. Not to mention the trouble you're likely going to have to go through from an ecu perspecive (the newer stuff has SO MANY other functions controlled by the ecu). Besides, while it might be rated at 300HP, with 3.7L - you're going to miss the torque of the V8 on the bottom.
I sent an e-mail to Accel Performance/Lakewood awhile back about a 3.7 to C-4 bellhousing and this is a copy of said e-mail with the response:I am also looking to swap my current 3.8L (in a fox) to the 3.7L. Does anyone know if the bellhousing on this engine is the same as any of the modular engines? I have a c4 with PA bell now. Was hoping I could use the c4 with a modular bell for the swap. Anybody have information or a link to what kind of internal parts this engine has and what is available from Ford for racing/high performance? Glad to see there is a forum on here for this platform I think it has great potential. Any information appreciated. Thanks.
