    Which is Better 331 or 347

    I built a 331 based engine for the fact of no pin in the oil rings, less piston rock in the bottom of the bores. Less piston speed. With a 3.250" stroke the piston doesn't come out the bottom of the bore as far as a 3.400" stroke. This is my opinion. I'm sure someone else will have a different...

    331 or 347?

    The difference in the two engines is the crankshaft stroke. 331 has a 3.250" stroke and the 347 has a 3.400" stroke. They can both use either the 5.315" or the 5.400" rods provided the have the proper piston compression heights.

    Question about the T-5's tail shaft bushing

    Transmission shops can change out the bushing very easily. For minimal charge. They have a tool that self threads itself into the bushing and then they slidehammer it out. Then they pound in the new bushing with a guide tool. It is a pretty straight forward job. They can do it on a lift in a 1/2...

    Who has a similar setup and what are you putting down??

    Just because you need emissions & use an emmissions legal cam doesn't mean it will pass. The cam is all wrong for that set-up. I made 390 H.P./362 TQ. from a 337 stroker recently with a 4 bbl carb. And a dual plane intake. It doesn't pass emissions but it sure runs good. Talk to one of the cam...

    Thinking of selling

    Any car can be a money pit! If you have a place to keep it,Take it off the road & Park it for 5 years. Buy something newer and have fun. Buy a beater econo box and drive that daily for the mileage reasons. I drive a P.T. Cruiser for my daily beat ride. It is not my first choice but it gets me...

    Front Fenders--80-90 and 91-93 or 87-90 and 91-93

    Yes there the same from 80-90. In 91 Ford put 16" rims on the Mustangs and they needed bigger wheel openings. Some of the 80-90 fenders were not drilled for the fender extensions.
