Help! 700r4 trans into 1963 corvette

[smitts]

Can anyone tell me if a 700r4 transmission will work in a 1963 corvette without any body modifications and if it does work is there a kit offered? I believe the driveshaft may be shorter and don't know about the mounting. I'm running a 300hp 327 with the old powerglide (2-speed).

Can't help you directly, but here's a couple of vendors that you might investigate; perhaps they know the answer:

Chris,

I am sure that someone has a kit out there available, but you'll always hear me plugging the 200-4r tranny. These days, Buick Grand National's owners have learned to squeeze the maximum from these trannys.

Now-a-days you can get a stout 200-4r for your Vette which is within an 1/8 of an inch of Powerglide dimensions. However, the driveshaft lenghts remains stock, and you'll only have to change the cross member support (the rubber tranny mount is about 5.5" - 6" aft from what a powerglide mount location is.

I have the Level 2 from PATC. As a matter of fact, I bought it and installed it a year ago. Runs like a champ.

Monster Transmission are very good as well.

Thanks for this info I'll do some checking. Is the 2004r an overdrive tranny?

Yes! It is an automatic transmission with an overdrive 4th gear. Its original design was excellent, but it suffered from weak points inside. By now, many true gearheads, have solve its ailments.

Bowtie Transmissions, Art Carr Transmissions, and others have made available a solid product.

Here is an interesting comparison I found through Gbodyforum.com
