Mastertech5: I'm also using an LS3 in my truck build and I was surprised at how little room there was for an accessory drive, and I consider the LS as a rather compact engine. What I ended up using was the Holley LS accessory drive system, I ordered P/N 20-185BK as the black fit my theme better. What I like about this system: no extra brackets, everything mounts to their water pump housing, and that housing has a provision for the LS steam line. Another plus for me since I not running a hood or side covers is the water pump has two options for routing the heater hoses, straight out like any other LS water pump, or down as I used. It helped to kind of hide the heater hoses IMO. One thing to be aware of: While this system comes with a power steering pump and related parts, there is no way the P/S would fit in the '33/'35 chassis - other FFR models I can't speak too. I wish it was offered without the P/S, but even with it it was a little cheaper than some other systems I looked at, now if I could only sell those P/S parts I didn't use!
