Hey fellas,

Has anyone used this (or a similar) race alt. mount? It looks to simple to me, like all the tension/weight is being held by one bolt.

I rather get the bmr one it. 2 bolts is better than 1.

I was able to alter it to fit my iron block, I'll try and take pics later today to show you how I did it.

I have a bmr one on my ls2, but if that setup there was available I'd have probably taken that route instead. Looks like a nice setup IMO

i use a std chevy alternator bolted directly to the front hole in the block, and a heim joint to tension the belt.
it runs off the a/c side of the crank pulley. its near perfect alignment.
7500rpm, no belt slingage.
ive run it with and without a backbrace, same results, but i have a lil homeade backbrace on it just for peace of mind.

Here's mine, BMR kit that I modified because I have a 6.0 block

TJ think your design would work with a belt to the water pump as well? More pics please I have an iron block as well.

Here's the one I use. It's by a non-sponsor, so just pm me for details. But it also uses a smaller denso alternator(considerable weight savings).

I still use the stock alt bracket and relocated the tensioner (something Tom the Roofer did many years ago which I copied )

mount the tensioner on the back side where the idler pulley used to be (have to clearance the webbing on the alt bracket). its held in by one bolt, but it sits tight against the bracket on the bottom so it can't rotate. Works so far up to 8000 rpm

Best part is that its FREE

you would need an alumium spacer to bring the alternator out to run on the 6rib so it would line up on the water pump pulley.
the pulley is pretty wide, but i dont know if it would stay on it or slip off the back.
itd doable for sure.
my alt is mounted directly to the block.


this is an older pic on my stock 6.0, but same setup.
