Re: New to mustangs and needs help!
Well, they are really the same motor (block). It's just that the 302 has a longer stroke set by the crankshaft and little bit longer cylinder wall to stop piston rattle, well the newer motors do anyway. At least that's my very layman's understanding of it all.
I would say 289 if you want to stay more true to the original design of the mustang. 302/351 if you're looking to make a racer but, that's gonna be a ton of money, time and heartburn.
The 302 is a great engine and as said above has a ton of upgrades available. I seriously looked at going 302 before a 289 pretty much landed in my
But, no matter which engine you choose, upgrade that front end suspension first!
