Low mount Alt ?

[DaHos]

In the process of planning my front drive accessories. Motor is 2010 w VVT (LS3/Truck spacing). I will be using a "car" intake and looking for opinions on the low mount alternator w /upper ps pump. Also still looking into water pump configurations.....any input? THX !!! FYI: 67 C10

I went with Holley's low mount, when using this specific mount and you have a 67-72 you will probably have to trim your frame for the alternator to fit, atleast this is what I found in my install. I ended up trimming about a 1/2 inch off of my frame, this did allow me to run a 140 amp alternator though.

On water pump I would recommend a 2010 LS3 Camaro water pump, with this pump the upper hose comes out toward the drivers side more like a stock 350 for these trucks. You can then run a stock style radiator with a hose that fits, this allows for a nice short hose. I have a hose part number (not on me at the moment) but haven't gotten far enough on my build to see how it fits.

The GM factory Cadillac front accessory drive setup is nearly identical to your picture. I'll post it on my LS3. It does run a low mount a/c compressor, which Vintage Air doesn't recommend, so I put a different high mount for the compressor, and used a longer belt. Works pretty well though. Am going to post a picture of it before I got all the sheet metal on so you can see it.

I found the GM system to be extremely cost effective. Think it was $800 with the alternator, power steering pump, and a/c compressor. I sold the compressor for $300, so I only had $500 for the drive system. Might have been too much, but was a bargain compared to to the March system I looked at.
