Is it an auto, or manual trans? It should bolt up, but will not last too long if the 350 has any performance mods done to it.

WAR,
If your V-6 is a 2.8 (pretty sure it is) then the trans will not work. The 2.8 trans has a different bellhousing than the small block. All this is assuming that it is an automatic.
Hope this helps,

Good point, I forgot about that darn 2.8. I just automatically thought of the 4.3. Thanks for setting me straight.

nick, the bellhousing flange on a 2.8 is completely different than a 4.3 v-6 or V-8. I believe there is a difference in the input shaft of the trans too. Best off to find a V-8 donor car.

If you want to keep a 5-speed in your car you need to get a 5-speed out of a 86-92 camaro with a V8. Also keep in mind that you can put a 6-speed into your car with little mods. Trust me I've seen it done.

Most 3rd gen cars with a 4 or 6 cylinder had 14 spline t-5's for manuals. The 8 cylinder cars had 26(?) spline. The v8 trans did not last long behind a 350 (IROC's were automatics), so you can imagine how lonf the even weaker 4/6 trans would last.

Do keep the six speed in mind. I have one in a 92 Firebird and love it. The swap was a cake walk.

Scooter, imagine if they had come with the 4.3's. Darn Camaros would have been as fast as the Vettes then....hey wait....maybe that why Chevrolet used the 2.8.

Mike Knell of Jaguars That Run, a very large engine/transmission swap expert, calls people who insist on using the 2.8 and 4.3 transmissions, both automatic and stick, with V8 conversions "totally suicidal" and shows a few blow-up w/schrapnel pics in his swap manuals.

Nick,
Fist off for the bolt pattern on the 2.8 is different then the V8's and even the larger V6's (why GM did this is beyond me)
Second if you have a factory 5-speed with the V8 bolt pattern it will not last on the 350. the 350 puts out to much for the factory 5-speed and it burns it up. the 350 and the 5-speed were not avaible on the same car from the factory.
you need a after market 5-speed. or just go with a 700R4

I will be making the same switch. I have done a ton of research one it and it will be difficult but thats not going to stop me!!

Hope this helps,
Chuck
