Admittedly, his belt was longer, but it was a nightmare. I convinced him to swap it for a vintage air serpentine system and it’s been trouble free ever since.

WOW, sounds like PITA for your dad. I haven't had any issues [fingers crossed now] and this Gilmer system has been on car since new. I was just doing yearly maint and found the belt was looser then before and wanted to adjust it. If I was having issues like your father I would swap it out also! I adjusted the belt with 3/8 deflection (engine hot). It is tiighter then it was but hopefully loose enough not to cause me a problem ... thanks again.

try looking at Jones or CV Products(big Nascar supplier in NC) or maybe even Street and Performance--- no need to do the $2500 setups

Hey Jerry - When I bought the car I was surprised to see belt system myself. Everything has always worked fine and I do like the way it looks under the hood. Backdraft did the engine install themselves and they still sell this same kit for their cars so it does work and has always been trouble free for me. I am just getting some maint done and car ready for the year when I noticed belt was looser then it was. I adjusted the belt with 3/8 deflection with engine hot.
My problem is I am an A&P Mechanic so in my world EVERYTHING has TQ value, and specs ... I am probably more anal then most owners/mech because of my background. My friends always busting on me for being "too precise" (their words) when working on bikes and cars ... their always telling me "it's not a *#%@^ airplane Don". I TQ every nut, bolt and screw on any ride I work on ...
