Which Engine?

351c or Boss 302 in my 70 stang to play this summer?

I was going to screw around with a 428 I have but damn they are a pita for mounts, headers and accessories

Either way it's going to have 3.89 gears with a C4

Hummmmm ?

302 just becouse it's easier to work on.

Pre 67 I would do the 302 for matters of clearances, post 66 Cleveland for sure, build it how you want want it...

351C,my cousin built a Trw flat top 351C 4 barrel closed chamber heads one year when he was laid off.Comp 294 Solid Cam,C-4 4,500 Converter but had 4.56 gears ran easy 12.30's every pass in a 74 Comet.

I vote Cleveland if you can stand the cramped space.

Cleveland.

Which generation Boss 302, 1st or 2nd? If the 1st Gen, I would go that route. After all, the Boss 302 was available in that car and it is a Cleveland headed engine.

He's got a "fake" Boss motor for it and the headers..

A no- brainer to me....

I would say that any engine family last mass produced in 1977 would become a less friendly engine to obtain supportive parts unless they shared supporting parts with a later engine family.

One hasn't been manufactured since 1970 and the other 74..... But I have a pretty good stash for both.

Vehicles in the U.S.A were manufactured with 335 series engines and parts through the 1982 year and the inline small block, (sharing the same mounting as a the Boss 302), was put in vehicles thorough 1999.
The aftermarket was much more supportive of those vehicles after 1980 with continuing bolt-on and conversion type parts for both; not the earlier FE vehicles.

You were bitchin' about not being able to easily get motor mounts and other supportive parts for a 428 vehicle and this is the reason.

Agreed...... The small block and Cleveland stuff is a whole lot more plentyful in mustangs then the FE stuff

With a C4 I'd vote Cleveland.

Now if you were to go standard then I say Boss 302
