yea i remember my dads 442 had a TH350 factory, so its doable some way or another.

Not all bolts well fit right. The chevy trans bell housing if different. Unless u have one of those multi bolt with both bell housing patterens it wont fit. But u can give a shout to transdapt they have a plat that well make it fit

[badinfluence]

You can buy an adapter to make it work. There like $100

Otherwise no

olds, pontiac, buick manual transmissions are hard to find either way

[beardy2]

well i decided to pass on it it was a olds rocket 350, i think i am going up to flint for a chevy 350 for $125 it is 1 1/2 hours from my house.

[badinfluence]

your still lookin for an engine?

I saw a "running" 305 on craigslist for $100

$125 for a 350 would be a better choice though

[beardy2]

yeah i am still looking it has been a little bit of a pain but i am still going to try to get ti done for the meet & greet but i dont know if i can do that since i do it all by myself.

[beardy2]

hey adam did you get my pm about that truck the other day beacause you never responded

[badinfluence]

dont remember that one, i'll go check my box

[TSTONE]

in the th350's there are 3 different flavors

chevy
BOP - Buick Olds Pontiac
BOP/C - a universal mount Buick/Olds/Pontiac/Chevy

summit sells tci adapter plates to go chevy to bop or bop to chevy - they run about $60.00

p.s. if anyone needs it I have a chevy motor to BOP adapter plate

Chapter 2: Transmission: Bolt Patterns

GM rear wheel drive transmissions were cast with a number of different bolt patterns to mate to various engines. There are three common bolt patterns. In many cases, a transmission with one bolt pattern will not mate to an engine with a different bolt pattern without the use of an adaptor.

Above is the "Chevy" Bolt Pattern. The high center peak at the top is it's most noteable feature. Transmissions with this bolt pattern will mate to most Chevy engines (most front wheel drive engines used a different bolt pattern not illustrated here).

Above is the "BOP" (Buick-Olds-Pontiac) Bolt Pattern. The depressed flat at the top is it's most noteable feature. Transmissions with this bolt pattern will mate to most Buick, Cadillac, Oldsmobile and Pontiac engines (most front wheel drive engines used a different bolt pattern not illustrated here).

The third common bolt pattern is what is often refered to as the "Dual" Pattern bolt pattern. Or sometimes called the "Universal" pattern. Transmissions with this pattern will bolt up to engines with either of the two patterns above eliminating the need to use an adaptor plate.
The lower two bolts and the locating dowels are in the same locations for both the "Chevy" and the "BOP" bolt patterns. The locations of the upper four bolts is different. The "Dual" takes advantage of this and provides for mating to either pattern.

where did you find those pics those are cool. i am not sure if i will be getting that 350 in flint he has to email me back and tell me if it is out of a blazer with 4x4 because if it is then i need to change the oil pan and the oil pump and the screen which i do not have the money for. so if any one finds a sbc 350 running for cheap let me know.
