Pulley question
Will the Corvette Crank pulley on a 350 bolt onto a 454 harmonic balancer?
I need the smaller pulley to fit in the car without modifying the crossmember.

454 with "Corvette pulleys" should fit in place without modifing anything.
its close.... so close its hard to get belts on, but it should fit.

The 350 pulley fits on the 454 balancer easy enough. It is even a little bigger than a Big Block pulley!
A stock 454 looks like this. And yes, I could probably force the belts on, but I really need a little more room to feel comfortable.
Anyone know a part number for a slightly smaller, maybe 7 inch 454 pulley?

They fit but check the alignment, prev owner for didn't check pulley numbers and put a bb pulley on when he added aftermkt a/c. Ps pulley was fine but alt pulley out by about 1/8" and would squeal above 3500 rpm.

Wow, those things are EXPENSIVE!!!!!
After reading and going through the thread referenced above and doing a lot of checking, I finally settled on what I believe is the right part.
Seems as if Marine applications use the smaller one.
But Amazon seemed to have the best deal around on a nice billet one.
Prices for these pulleys is obscene.

Got this billet aluminum pulley for 46.00. It fits the 454 harmonic balancer perfectly. 6.75 inches across.
Some of the pulleys for this motor are pornographically expensive. It is possible to get one cheaper, but this one seemed a bit nicer for not much more money.
I will match the water pump, alternator and P/S pump.
I don't care about the smaller pulley as I intend to run a small oil cooler on this car.
