What is the correct size alternator?

[lakemeadzmonster]

I think its 124 amp for the 1990 ZR-1 but I've seen other's listed all over 105 ext. and one on Ebay is at 200 amp Delco High Output $95.00 and the same place offers a 124 amp $65.00 would this be a good upgrade or stick with the 124amp?

Any ideas?

Thanks

The Plenum pull goes on. But it going to be right. I'm still looking for the pvc hose and connector.:confused:
