LT1 alternator bracket and alternator questions
I have a 1992 corvette and I am putting in a blown 383 stroker. The engine is in and most of the stuff is coming along nicely but I am having a few minor issues. I am using AFR 210 heads along with some Jesel Shaft mount roller 1.6 rockers. I ordered some canton aluminum valve covers that are supposed to clear the alternator on the drivers side. Well the problem I am having is the canton cover hits the stud and shaft of the rocker on the drivers side front were the valve cover is modified to fit the alternator. I am going to cut and weld the valve cover to make it fit but I don't think The alternator is going to clear the valve cover after I do this. I am wondering if anyone out there makes a different alternator/ac/ps bracket? I have decided to delete the ac all together so a new aftermarket bracket would clean up the mess that gm made with that bracket setup. I have done a little searching and I haven't found anything. The only other option I think I have is buying a smaller dense power master alternator that would clear. If anyone else ran into this problem or has any ideas, you input would be appreciated!

The smaller alternator from power master is out of the question. They dont make one! So I do have another idea. I am wondering how far I can clock the alternator before it hits the hood. I think I can make a small bracket that will clock the alternator enough to clear the cover. Unfortunately I dont have the hood on my car right now and checking clearance is not an option. Can somebody please check the clearance from the top of their alternator to the hood with it closed?

I don't have an LT1 to help you but are you asking that someone perhaps use some modeling clay, playdough or similar product and do the hood close? I'd think that very doable by just using a plastic bag or plastic wrap to protect the alternator and the modeling clay to do the mold. If I missed something here mention it please, I guess maybe you could remove fender panels, the wheel and measure but the "hood shut" on the modeling clay/playdough just sounded like the best and quickest!

Here's a long shot, but it worked for me. My alternator (or diodes) failed while on the 2003 50th Corvette Caravan. I was taken via roll-back to a Chevy dealer in Portland, Tenn (I think), off of I. 65 just south of the KY border.
Anyway, it was close to 5:00 PM on a Friday. The dealer did not have a replacement in stock. The parts mgr. called all over the area to try to find an alternator, but had no luck. Then the mechanic approached us and said he found a similar alternator on the rack and he thought he could make it work. All the electrical specs fit, but the physical size must have been larger. Anyway, he said all he had to do was to remove the alternator mounting bracket and "flip it over". A half hour later I was on my way to Bowling Green.
It's been 10 years now on that same alternator with no problems whatsoever. Sorry for being long winded.
