OK, I know I can make it bolt up together, but the T-5 I have is rated for 330 ft/lbs of torque. It is a World Class tranny, brand new. I was planning on putting it behind my 289, but now that I'm getting another project car that needs a V-8 instead of the I6, I'm thinking about the 351 in my '66 FB and the 289 in the SWMBO's rag top. If I go 351, it will have 10:1 comp., Trick Flow Twisted Wedge heads and the Edelbrock Performer RPM cam and intake. I know that this produces a lot of torque, and I don't want to trash a perfectly good tranny. Anyone here have the T-5 behind a hot 351? Cannot see giving the wife a 351 in her soon to be '66 Conv.!

I wouldnt recommend putting that 351 in front of the T-5. People are doing it but i dont know how well long it will work... I think if you were be doing any racing/ higher performance driving to get a TKO tranny. Your engine is probably pushing closer to 400-430lbs of torque. I would sell the T5 and buy a TKO.

I will agree with the previous post unless this is a daily driver and you dont plan to do any burnouts at the next cornfeed...

I had a T-5 behind a 351 for a long time. The tires always spun easy enough that I never broke the transmission. If you plan on bolting on a set of slicks to race with, forget it then. I had this 351 in a 65 fastback, so it might be a lighter car than what you're talking about too, I don't know. The car I am talking about here ran an 11.70 quarter mile, at 121 mph. This was done with 8 inch slicks and a four-speed though. I do know that power shifting these T-5's destroys them quicker than anything else. Lift that right foot when you shift and you'll probably be just fine.

Bottom line (IMO) is - why have a 351 if you are not going to use the power? If you use the torque made by a W, you will trash a T5, sooner or later. If you baby it, you might as well stick with the 289.

The guy that owns the bodyshop where my car is being worked on, has a couple of sons that are seriously into 5.0 Fox bodies. His shop is often a hang out for these kids and their friends on Saturdays when the6y get together to assess the damage done to their cars by Friday night street racing. On several occasions, I've seen these guys pulling apart a "World Class" T5 and wondering why they managed to trash the thing with their 350 hp 302.

If a 302 can tear up a T5, a Windsor will eat it for lunch.

I would suggest a Tremec if you have to have 5 gears.

And...if you will be "exercising" the power of a Windsor, you should also consider upgrading to a nine inch rear.

Thanks guys. This was my feelings, just wanted to hear everyone elses opinions. I'll stick to the 289 as I planned to.
