700r4 vs th350

Hey all. just have a question want some opinions ive read both bad and good about both. I have a 700r4 transmission wich i probably have to get rebuilt, whats the average normal price to get one rebuilt? Also im thinkin about replacing with a th350 tranny , whats the pros and cons on the th350 vs the 700r4 and what kind of differences will swapping to 350 make, also if i do swap to the 350 what kind of changes will i have to make to the car, i have an 87 camaro z 28 5.7 350 v8 TPI.

700r4 has a lower 1st gear so you can run a taller gear ratio and still get off the line, is more costly to rebuild, and is longer than a th350.
the cross member/tranny mount will have to be moved and the drive shaft lengthened.
i make no claims as to be an auto-magic transmission expert, and i have never made a swap like this. how ever, i believe another member who has will correct me if i'm wrong, and provide in depth details.

I like the 700, for the reasons stated above, plus the OD will return some half way decent gas mileage on the highway. As far as a rebuild, you want a 87 or later core, the earlier ones had design problems. I just purchased a 700 for my 34 project for $750. This was not from a transmission shop, it was from an individual that has a very good reputation in my area for rebuilding 700's for performance cars. He even provided the core for $750. If your transmission does not need any hard parts, such as planetary gears and such, the rebuild should not run more than that. I got a 700 with Kevlar clutches, bands, Corvette 3rd & 4th gear servo, Corvette 2400-2500rpm converter, new detent cable, new filler tube, new dust cover, and a switch to control torque converter lockup.

I could not find a 700 on the internet for less than $1000 and that was without a converter. I would suggest you ask around in your area and see if there is a recognized rebuilder that does them for rodders. I would be real hesitant to turn it over to a transmission shop, unless you are very familiar with them.

FWIW the person that rebuilt the 700 that I bought has a 70 Chevelle with a 572 GM Performance crate engine in front of a 700 he rebuilt. I don't think my Fastburn 350 will harm the 700 I have.
