BTW,
Today I got her all cleaned up and took her for a ride. While I was out, I got some pictures of my Vette. Here they are. Again, thanks for all the help with my belt issue.

The bracket that his vehicle had was a modified stock unit.What I have seen with other customer vehicles is that a modified stock bracket is good for low 500 rwhp.
GM makes one that is closed in the area where the idler is but I have tested it and seems to be good for about the same (brakes on the bottom of the bracket).The ECS is a great piece for the vehicles having this problem.
I have had a complete billet alternator brackets made for some clients because there vehicles made well over 600 rwhp and started cracking and braking the stock brackets where the alternator would holed on too.This using a small bracket (off a 1997) corvette that holes the alternator to the head just to keep things from moving.This bracket has worked fine for my clients even for producing very close to 800 rwhp on a s/c application.
One thing that I do recommend is to replace the stamped metal idler pulley with a solid pulley pulley because they will crack and brake off.
With regards to the pulley alignment,the only pulley that needed alignment was the tensioner.Everything was aligned.
The vehicle should be doing over 550-560 rwhp but the quality of fuel that he has in his town is not the greatest.So I rather sacrifice horse power for a safe program any time.
When we started dynoing the vehicle,we picked up 8 degrees of timing retarding at less then 4000 rpm's but the car still made over 450 rwhp.We had to add premium fuel so we could continue tuning.
His vehicle did 538 rwhp but still pulled timing because of the bad gas.With the right fuel this vehicle would be well over 550 rwhp and that is at just about 8 psi of boost.
