6.0 and 5.7 harmonic balancer's interchangeable??
 

Doing a quick online parts store search, part numbers for a stock 6.0 and a stock 5.7 are different.

I have an F body, that retains it's stock 5.7 accessory drives, but somewhere along the way, somebody swapped on a 25% underdriven balancer/pulley....less than 6" O.D., which means the alternator is not charging at idle, plus I want to re-install the AC that the previous owner removed.

I do NOT want an underdriven crank pulley, and want to replace it with a STOCK diameter version, and either a factory one, a decent replacement, or a stock diameter SFI-rated version...

Just unsure which ones are interchangeable, or if it doesn't matter and I can just order a new one for a 2000 Trans Am, and not worry about the base engine being different than what it came with???

I'm also having problem trying to locate the thread on this site that lists all the various hardware bolt lengths and part numbers...I found an AC bracket bolt kit online, but also need whatever bolts and nuts to secure the condenser, and receiver/drier, if anyone can steer me...

Thanks.

Awesome! Thanks a lot for the link. Sucks searching (or trying to) on a phone. :burn:

Now if I can find some AC related hardware answers, my project can go forward.

I appreciate the links once again...unfortunately, I didn't see any mention of hardware in any of them.

I have all the bracketry, and everything that came off the car, as far as A/C parts, but the previous owner couldn't find the bolts/nuts to everything that he had taken off.

I just ordered the compressor bracket bolts, and the tensioner/idler bracket bolts, so I have some...just need, mainly whatever holds the condenser in, and whatever holds the A/C lines together, and stuff like that.

I guess since I have the main ones already sourced, I'll just make some hardware store runs...lol.

Thanks!
