What are my options for 350s in a '91 Camaro? Is a Chevy 350, a Chevy 350, is a Chevy 350 as far as engine mounting and trany mounting, or are there differecnces? Thank you in advance for your help.

-'91 RS Chevy Camaro
-'73 Nova Custom
-'76 Toyota Celica GT

 

Engine and tranny mounting, correct - no differences.

But...

Intake, cam, flex plate - that's where the differences are: '86-earlier different than yours for the first two, '85-earlier different for the latter.

Of course, there are sedan 350's, truck 350's, performance 350's - now you're getting into a real "mouse" trap.

------------------
82 Berlinetta, orig V-6 car, now w/86 LG4/TH700R4. 2.93 limited slip. Cat-back from '91 GTA, ZZ3 intake, Accel HEI SuperCoil. AMSOIL syn lubes bumper-to-bumper. Daily driver, work-in-progress (LG4 w/'87 LB9 block, ZZ3 cam, ported World 305 heads, Hooker headers & y-pipe, 3" Catco cat & 3" cat-back).
57 Bel Air, my 1st car. '66 396, 9.7 CR forged TRWs, Weiand Action+, Edelbrock 1901 Q-Jet, GK 270 cam, Magnum rockers, Jacobs Omnipack, 1-3/4" Hedders & 3" Warlocks, TH400 w/TCI Sat Night Special conv & Trans-Scat shift kit, MegaShifter, 3.08 8.2" 10-bolt w/Powertrax, AMSOIL syn lubes bumper-to-bumper. Idles smooth @ 600 RPM in D. Best 15.02/95.06 @ 5800' Bandimere (corrected 13.93/102.4 @ sea level).

 

I plan on swaping the 3.1 for a 350. On my desktop dyno software it says it'll have about 480hp with everything I'm getting. Later I will add twin turbos, but not for awile. So basicly all I need is a 350 block and then go from there and it doesn't matter where I get the block from as long as it's a Chevy right?

A Target 350 block, cast in Mexico, may not be the ticket for your dreams. Perhaps you should consider the World Motown block instead. It's $1700 plus tax & shipping, but it should hold up to the abuse you're about to heap on it.

2-bolt, 4-bolt, splayed caps, forged crank, roller block, flat tappet, internally balanced, hypereutectic, one-piece - heard any of these terms? Understand what they mean? Not to flame, but if not, you've got a lot of research to do before you take off on this kind of project.

 

I was thinking about pulling a block out of a salvage yard and having it bored out rather then getting a new block as I am on a budget. This will be my 3rd engine build/swap, so I know what I'm doing. I just havn't done swaps in newer cars and wasn't sure if there were differences between blocks. What is the best trany for what I want? I was thinking of going with the turbo 350 as I am very pleased with it's performance in my Nova, but if there is something better then please let me know. If I get a post 86 block will heads from a pre 86 work, or are there differeces? Thank you for your help.

Not trying to sound like a smart a$$, but go to Barnes & Noble and get this book;

Title- Chevy Parts Interchange Manual
Author- Ed Staffel
Publisher- Cartech

It'll answer a lot of your questions. This book (nor any other in the world) doesn't have all the answers to SBC questions, but it covers a lot of more "common" ones.
