100 amp C3 alternator

Re: 100 amp C3 alternator

I'm resurrecting this post just to get some quick insights about insertion of the original fan shroud.
I've removed the spal fan assembly and the rad sensor so all the electricals and original (new style) clutch fan are in place.
Before placing the fan/clutch on I couldn't see how the shroud could go on. I'm wondering what's the minimum equipment to remove to get the shroud back on. Looks like the water pump pulley might have to come off but want to check before I start ripping apart more than I have to in case someone has a technique I can't readily see.

By the way, with the new clutch/fan assembly, the Dewitts rad and without the shroud the temperature barely broke 150f. Love hearing the fan growl again.

Thanks all for the guidance.

All I can tell you is that installing these shrouds even in a completely stock configuration is a big time bitch.

The GM #88961768 fan clutch (originally GM #343721) is the best performing fan clutch EVER for a Corvette. It definitely "growls" because it's pulling a lot of air. That's music to my ears. This fan clutch requires other mods to be used on a pre-1971 Corvette and it certainly does not appear anything like any pre-1971 fan clutch but if high performance cooling is what one seeks, it doesn't get better than this.
