clocking the alternator?

Hi folks,

I'm in the process of a 350 upgrade, and as part of it, converted from the old V-belt to the serpentine setup. However, now that I'm wiring up the engine, I discover that the 12V output on the back of the alternator interferes with my perimeter bolt valve cover (pre-87 style AFR heads). A friend mentioned to me that I can clock the alternator so that the output is in a different location, and a search shows that this is a pretty common procedure. What I didn't find from searching is what happens with the support bracket? My alternator has a stud on the rear where a thick iron bar attaches the alternator to the headers for support, if I clock the alternator then this changes the position of the stud, and I'm not sure I'll then be able to attach a support to anything.

I assume with all the interest in serpentine belt conversions, someone has run into this issue...any suggestions? I'm not necessarily averse to buying a new alternator, or taking mine to a shop to have it modifie, so suggest away.

Thanks!

there is a large plastic (sometimes metal) cyclinder that is in most homes nowadays i beleive it's called a trash can some times call a garbage can.that is were i put my bracket when i on my headers.i'm sure there was a good reason why the designers felt this brace was needed.the Alt. is braced pretty good with just the two mounting bolts.

Awesome. I couldn't wiggle the alt. with both bolts installed, but I wasn't sure if it'd cause problems. Sounds great guys. I just got back into town yesterday, picked up my alternator, it's re-clocked, rebuilt and 1 wire converted. $75 but I think it's worth it for an alt that fits and some peace of mind that this thing is going to last a while.

Thanks again
