Which you do you think will get better gas mileage?
1. 400 inch motor, 4.56 gear, 5000 stall, big cam. 2. 400 inch motor, 3.55 gear, 2500 stall, small cam, 76 mm turbo.
Everything else is identical with the exception of noted above.
I am curious as to your reply.
I think the premise is identical engine, just add turbo.
Exactly, which is the original posters intent and what we were discussing!
I'll answer the question for him though- The motor with the 76mm turbo will get better mpg since it has a mellower cam, milder gear and less stall on the converter.
