I need to know if this

"350 4 BOLT main, 120,000 Kms, one piece rear main seal, excellent motor,"

would work in my 86 camaro, i Will be putting in a TH350, keep in mind i know nothing about rear main seals.....

 

The flywheel bolts into the crankshaft and the flywheel bolts onto the torque converter. The RMS doesn't get in the way (shouldn't).

The difference is that a one piece doesn't leak as much.

 

Yes it matters greatly. The bolt pattern on the back of the crank is different, and therefore the flywheel or flex plate does not interchange between the 2.

Your 86 should have the 1-piece (1st year of it). So that block should fit. However, if it doesn't, just get the right flex plate for it. The 350 converter will bolt to a stock 700 flex plate.

 

Do you mean 700r4 by 700? cause i wont have one anymore, it'll be TH350...

oh wait, i think i got it, The TC from the TH350 will bolt to the flex pplate i have now?

 

Yes, basically that's it. The 350 converter bolt pattern it the same as the 700 converter bolt pattern, so the 350 converter will bolt to the stock flex plate for one of these cars.

 

thanks a lot, what would ahpppen if i found a 2piece rms, would i need a new flex plate?
