Who makes that pulley and bracket set up. I like the looks of that, and it gets rid of that serpantine belt set up.

I also like the belt setup. It looks good.

Is that the stock brackets, just modified? Everything looks clean and neat. Good job

BTW, that's not a stock serp. belt water pump, right?

Stock runners are going to hold you back.

Belt/pulley setup looks like gussied-up version of my '86 LG4 & '87 LB9 w/o AC. Alt. belt is flat multigrooved like serpentine, but doesn't "snake" around anything.

The belt system is the same, what came with my car stock...not the serpentine system. THe pullies are BBK's for 85-87 camaros, I got them cheap so couldsnt pass it up.. those years have a diffenent belt setup. I just cleaned everything up and made it look alot nicer. I like my braided fuel lines too. THe guy used my stock connectors, cut them off and added braided lines...a whole lot cleaner. My A/C brakets are there I just dont have the compressor hooked up yet...gonna leave that off for a while.

any idea on the HP gains?
