what year did the SBC go to the 1pc rear main seal?
Just curious if anyone here knows. I'm searching for a 1pc rear main 2bolt 350 block for a rebuild. I have a 2pc, but since I'll be using a f-body 6 spd, I'd rather save the $$$ than spend it on the centerforce flywheel needed.
Anyone know for sure?

However remember that no Camaros were produced with a 350 in 86, they were all 305s. SO if someone tells you they have an 86 f-body with a 350 they either have a swap or they are lying. GM didnt put 350s back in them till 87

Well, I wont be looking for a whole car - just a shortblock. With the heads off, I should think I can ID the 350 vs. the 305. Thanks for the advice though!

I've always seen the Car V8's had a one-pc seal in '86, but trucks had either or. It's confusing b/c of all the replacement engines with 2-pc'ers and production engines with 1-pc'ers floating around together. A lot of warantee replacments etc..

In 1986, Chevy started with the 1 piece rear main seal, but left the standard 4 bolt flange valve covers and the flat tappet cam in the motors. In 1987 GM changed to the centerbolt valve covers and roller cam. I spent many years working at parts stores selling replacement motors (and taking cores back), working on F-bodies and then did a few years at Jegs in tech support (for anyone who wonders who I am and how would I know). However, the 1986 block castings are not setup for the roller cam. So, you may want to consider a 1987 and up block to save money on the roller bits.
I've seen a few truck blocks with the "bosses" and the deep lifter bores for the roller cam, but the bosses weren't tapped and it didn't seem to be worth the effort to tap them for the conversion.
Hope this helps.
Good luck!
