Has anyone else had problems with repro engine belts? I just threw off my Alt belt after a high RPM joy ride. I KNOW I had it tight because I HAD to get it VERY tight to stop it from squealing. This is the 2nd car I've had where this happened with a new repro belt. I'm assuming these must like to stretch and need to be checked daily. 
Yep:
They are terrible. Especially bad on stroker engines that have a lot of grunt.
But they work great for getting on and off the trailer.

I actually bought my belts (1970 Challenger 440 Alternator/ Power steer belt) from good 'ol Mother Mopar! They are STILL available & say MOPAR on them. Just not "incused" like the old syle belts. My

I looked into carring these belts. So I bought a set for my own car.As a test trial. I had nothing but squeeking , squeeling and they wouldn't stay tight.
I have one customer whom in order to get his to stop squeeling he burnt an alternator bearing up it was so tight.
I use the Mopar brand belts (supplied by goodyear btw) and not worry about 'someone elses approval - or points'
If someone needs the info, I have an old Mopar brand belt/hose guide to look them up if needed
Yep, Bill you nailed it. I did the same thing. They at least say Mopar even though they're not "correct".
If memory serves me correctly, most of the OE belts were 11/32" in width. I had a hard time at the local parts store finding one a decent length that would work, so I got a 10/32" and used it on one of my cars. It was a closer length to the original and fit in the groves better. I think it might have been a smog pump belt or something. Anyway, several high rpm runs later and it hasn't been thrown. Just a thought for you guys like me that love WOT !

I picked up a new Gates belt, but I don't like the "cogged" teeth on it. Does any other company make one w/o the teeth? Mopar brand maybe?
Thanks
i think i got dayco belts, i said in an earlier post that it was gates but i was wrong. i'll have to check to be sure. that was one of my requirements, no "cogged" teeth.

I also burnt up an alternator making the repro belt to tight. I ended up getting a different back on my original alternator when it was redone and lost my numbers. A repro belt is not even that good for pulling on and off the trailer. You can't even rev it a little bit sitting still. I have had no problem with the Mopar belts. They may now be getting harder to find from your dealer?

However, the old Gates belt (from the previous owner circa '82) would always hold up just fine 
...Is there any quick reference in the mopar belt's number system to identify the available sizes ????
