The 86-93 Mustang V8 T5 is the stronger version, and will bolt right in to a 64-73 Mustang, with the adapter plate or T5 bellhousing and special T5 rear crossmember. It should be fine, as long as you don't beat the snot out of it.

Getting 500HP out of a 302. Now that would be impressive for a street car. Not to mention extremely expensive. You have a whole bunch of options for that motor as far as transmissions and since you are going to drop a bundle on the engine you might as well get the transmission you want. Good luck.

I don't see the point in spending all the money of the T5 conversion, having it fail, then having to spend the 2,100. Then instead of spending 2100 once your spending that plus the cost of the T5 conversion, but that's my opinion.

The OP didn't say anything about 500 hp. He's planning a 347. A T5 would hold up to a 347 as long as he didn't beat the crap out of it.

I don't know too much about T5's but i don't think it would handle that much.

Hmmm… missed that. Wonder how he's planning to get that much from a 347, NoS or a supercharger? It's gonna be real expensive either way, he should step up and get a stronger trans, $2100 bucks is nothing to a guy who's supercharging a 347 custom engine.

Yeah i was some what confused on how he planned to get that much. The most ive seen a 347 produce was in the low to mid 400's.

I want to know if I can put a T-5 in my 73 mach 1 it came with a 3 speed manual can I use the original 302 bellhousing? Will it bolt up or what mods will I have to do?!

Yes you can use a T5. You will either need to modify your existing or get the T5 conversion crossmember, shorten your driveshaft, and do a cable clutch conversion.
