Default Roller Cam

Guys,
I want to swap my stock 350 engine from my 1972 Corvette. It has a stock 4sp manual and probably is not a Muncie due to it being "K" stock VIN. I'm looking into a roller cam set up. Any suggestions on engine block I should go with? One that will mate up? I'm thinking a vortec block (1996-99). I'm not sure so I need your expertise please!!
Paul

If you want a "crate" engine the Vortec L31 4 bolt main is a lot of potential for the $2000 base price tag. A cam, valve spring, retainer, intake, electric fuel pump, regulator and exhaust upgrade will get you 350 HP and it is all new GM. http://gmpowertrainwarehouse.com/12530283.asp

Looks good, but the main question is will it mate up to my stock 4sp manual tranny?

No problem. Need a 1 piece rear main seal flywheel. If your trans is stock it is a Muncie. if you need a 168 tooth flywheel this one works. http://www.summitracing.com/parts/zz...make/chevrolet

there's a similar one I was looking at before I decided to work with my existing block: http://www.jegs.com/p/Chevrolet-Perf...69813/10002/-1

It's a new GM 383 roller, vortec heads. Forged crank instead of cast. Costs more than twice as much as the one above, though. Others warned about vortec heads limited maximum lift... so keep that in mind.
