Will either a cs130 or cs144 alternator fit my 1968 442 alternator brackets? Thinking of doing the swap/upgrade!

 

Get a 12SI. They can be had in stock form up to 94 amps and will bolt in just fine.

The CS130 will. I bought one that is shown as a stock replacement for my 1988 Oldsmobile Cutlass Supreme Classic, 105 amps. Good luck finding a true 12SI replacement. Most are 10SI chrome case alternators which get very hot and don't last. I also see 12SI fans on 10SI cases and vice versa. The aftermarket should have copied the 12SI, the better fan and more open case was done for a reason, improved cooling with higher amperage.

 

This is what I put on my 71 98:

Surprisingly, the OE alternator posted above is listed for the same price as the one at Jegs. I'm happy with it so far.

 

Thanks guys! I already upgraded the charge wire to 6 gauge. Should I put in a maxi fuse? If so where should I put it and how many amp fuse? I'm looking at a 140 amp alternator I have dual 18" electric fans and electric fuel pump.
