LT1 crank pulley question
While removing the crank pulley earlier, I noticed it had cracked at the webbing where the puller holds, and I mean straight through so no choice but to replace it of course.
Question is, is it interchangeable with the SBC crank pulley?

Only reason I asked if its interchangeable is because an SBC crank pulley would be far easier to source at this part of the world.
I believe they are zero balanced as every pulley is.

I am going for an LT1 specific, but IF and thats a bold IF, the SBC crank pulley works then sourcing a replacement will just be easier.
Been looking at aftermarket units, quite some $$, but some are cheaper than the GM replacement.

If you're saying the hub cracked where the balancer bolts to that, you can get a billet hub and balancer from Jeg's.

My hub is in great shape, its only the pulley that got damaged. I will take a picture and post it up.
I could get one off e-bay, but shipping to here is quite expensive.
First I will look into how much the stealership will charge for one, and then try to dig one out from the scrap yards or something. If I can't find one here, I will order one off Summit, but I am not wasting 300$ on an ATI lol

Been using my bbk underdrive pulley for around 8 months the way the instructions told me too which was to take my old one off and put on the bbk underdrive pulley and everything has been fine. Doesn't say anything bout needing a balancer to go with it. But hey that's not what I know, that's what bbk says.

Have you had any problems with your electrics? I have seen other cars have alternator problems with underdrive pulleys.

So its pointless then. I am picking up an OEM from monster81 tomorrow.
I am trying to focus on getting a stall, gears and rebuilding my 4L60E, and then my next purchase will be a motorbike (or I just drop the idea of the stall/gears until I break my trans).
