Default a question.... 327's

Hi guys, me again...

Can you sleeve a 350 down to 327? i'm just pondering something.

And... anyone have any links to those sb chevy powered Corvairs? (That's what i'm pondering, and no it wouldnt get the vettes engine :nono: )

The 327 and 350 cubic inch Chevy engines both used a 4.00" bore... No need to sleeve anything. The difference in displacement was due to the crank stroke (although there are journal differences to deal with). For a street engine, I can't see any advantage to reducing the displacement... Go with the 350.

And... anyone have any links to those sb chevy powered Corvairs? (That's what i'm pondering, and no it wouldnt get the vettes engine.
A company by the name of Crown used to make a conversion kit for the Corvairs, although I haven't seen one for sale in ages. I'd get in touch with CORSA, which is a Corvair owners organization... I would imagine that one of their members could point you in the right direction.

Good luck with your project!

Regards,

The 327 large journal crank (fits a 350 block) is a rare, expensive beast. If you want a revver, thats the ticket, because you can use the 4 bolt block and make a stout lower end.

As for the mid-engine 'vair, get in touch with Clark's Corvairs on the East Coast. They have the kits in stock, but they may also have a line on a car that has already been cut up. Gotta tell ya, these are the ultimate sleepers. Guy at Sears Point has one that is well diguised, running a 400 small block that just terrorizes the coast road. Good luck.

Hmm, what about my dad's large journal 302 crank? I wonder how that would work in a 350... :D

The Corvair coupe unibody is pretty rigid and you put a full cage in it with struts out to the suspension pickup points it'll be rock solid. With the V-8 you give up a cross-bar, but the rear tube frame makes up for it. As long as you use a '65 or later, the "safety" issues are not a problem. What rear gear assembly 'ya considering?
