Think the transport will be to new, I have old style, V belt and three wire

Looked at the search results for Transport and still didn't answer my question. Yes the Pontiac transport had a high amp alernator, however changeing the pulley and splicing the wires aren't my idea of a swap. If I was building something then yes it would work but I'm putting it in my daily driver and I just need the highest one that will bolt in.

i believe it is SI style alternator, the older style are SI series....if u search jegs or somewhere u can probably find one for you.

Jeg's or Summit will have some that are "stock." Do a little research on a CS-144 and you'll probably find one cheaper than stock and give you a couple of options as well in idle & maximum amp output.

The Transport one is a drop-in on smallblocks. If you can't splice two wires, matching color, then any big alternator may give you trouble

However, it's moot 'cuz it does NOT drop in on bigblocks ...at least, it didn't on my '74.

As mentioned, you have lots of options including purpose-built ones.

I am doing a CS130 alternator on my '75 K10 w/350. I got it from a '92-'95 Caddy. Has a 6 o'clock and 12 o'clock mounting. There are a few mods that are SUPER easy to handle. If you can wait until tomorrow, I will post EXACTLY what it entails.

Well I found a few that work, 1988 Suburban with all the bells and whistles is a 94 amp with a serpentine pulley. Change pulley and it bolts in, not the one that I got. 1978 Chevy Caprice with all power, 100 amp its bigger and has a different mounting bracket. part number 7157 at checker might have a A in front of it.

So instead of going the easy way, the 94 amp which the auto parts store would have changed the pulley for me I went the hard way for the extra 6 amps

Modified the bracket and cut the old bottom bolt bracket to use as a big washer and bolted the alternator in. I had some too short wiring issues but other then that it fit fine.

I did find out the nice free Optima yellow top I got is not holding a charge for some reason, but it was free

The reason that I modified the top bracket was the new alternator is 1 1/2 inches bigger and the top bracket would not have let it fit. With some serching the factory bracket would fit a small block but not the big block, this is in a big block.

Welcome to the wonderful world of autoparts store's alternatores

I've been through four "all new, lifetime warranty" NAPA alternators in four years and I think my current one is on its way out. It charges, but only at 12.4 volts.

I can't imagine it being anything in my truck, it isn't draining the battery while it sits.

So far I can't convince NAPA to warranty this one (they claim it has to charge more than 13.1V to pass their test ) but the second I can warranty it in CO I will just get my money back and buy an aftermarket one. Every other alternator failure I've had has been far from home

My advice would be to get an aftermarket (new) alternator.

Well the saga has ended for now!
Turns out that the Alternator was good so was the replacement that I put on my wireing had melted a bit around the junction box three of four bit the the big one. So I drove home with no alternator in the truck, ran fine . got home and put a F--d part in re ran all the wires that had anything to do with charging or starting and fixed it
