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.!
