what part do i need to hold the sproket onto the crank shaft, i see its a pin that slides in, but what ALL does on the crank shaft. i need to know what i need to order. Thanks

a woodruf key, prolly less than $1. not sure if it takes the straight one of the curved one. you should be able to tell from the cutuot on the crank.

there are 2 curved ones on a sbc, not sure about the caddy

That is called a "woodruff key". I don't know if there is a specific name for it as applies to chevy motors, but if you tel someone who knows, that you need the woodruff key that goes on the crankshaft they should know what your talkin' about. If you're ordering it at Kragen or other parts store, good luck!

Ha! beat me to it. BTW to figure out the size you need, just measure the width of the gap with a mic, prolly somethin' like an 1/8" woodruff key. I think home depot has them in their hardware swection in the drawers of plastic boxes with the specialty hardware in it. My local True Value carries them, bith straight and curved.

Yes a harmonic balancer will go on there after that sprocket here's a overall pic

better put the timing chain on after you install camshaft then the timing chain cover before you install the balancer. also when you install the balancer use an installation tool. some guys will just pound them on.

are all balancers the same? or do they make better ones? i see a lot in jegs, but not sure /forums/images/graemlins/peace.gif
