will a 700r4 bolt right up to a bbc 454? i was told that the 700r4 drags a little bit between shifts on 2-3 and 3-4, is this true because of the difference in ratio's of the tranny gears?

I don't know if it will bolt right up to a 454,
but the one on an old 350 I had sucked.It couldn't handle the power even witha shift kit.

I don't know about the bolt-up to a 454, but I do know that I was happy with the one I hooked up to my 350. I had a shift kit in it with corvette servos and a manual lockup switch with no problems in any gear. The car (81 monte) gets 15 mpg in the city with 25 mpg on the highway.

while we're on the subject how rare are the 700r4's cause i;m looking to rebuild the th350 in my GP but i would like an overdrive gear for the highway plus the lower first would help for my launching ( or lack there of). thanks. i now a guy who stuffed a big block into his 86 ss. it's in and humming but it took a lot of work. worth doing cause it would be fairly unique.!!!

The 700 will bolt up and qutie a few people have done this already. As for the shifting , i am not sure. I have heard that the 700 was not as strong as a lot of people thought, dont know if there is any truth to that.

This is a site that I found a few years ago. I have not had the need for a 700r4 yet but this shop appears to have a good product.

I find the shifting on the 700R4 to be quite satisfactory. With a stage 2 shift kit in mine, it shifts with quite a good tire squawk into second gear and a good solid 3rd gear shift, downshifting is also good and solid. Comparing my 700R4 to my old turbo 350 I would never go back to the 350. Having that extra gear for on the highway increased my gas mileage by at least 8mpg, and the better first gear ratio is great for that extra jump off the line. They're definitely worth the changeover.
