Good solid mount but needed modification

January 06, 2013
I bought this alternator mount for my small block chevy. I'm running Speedways's 3 9super7's intake set up. Looks great and very solid mount but i had some issues. The First problem I encountered was that the fuel line for my front carb is very close to the rear of my alternator and can rub. Causeing a dangerous fuel leak that could start a fire on the alernator making electricity. The second problem i found was when it was time to tighten up the belt. If you adjust the belt tension too much. The adjuster hits your fan on your alternator. Also the belt contact the 3 bolts that attaches the mount to the head when running. Needed to counter sink holes and use allen head bolts.
Pros:
  • high quality mount
  • Easy To Install
Cons:
  • adjuster hits alterator fan/pulley
  • Expensive
  • belt hits bolts that mount bracket to head
  • alt to close to fuel line entering carb
Yes, I recommend this product.

Very Nice piece

April 07, 2011
If you have a very narrow engine compartment like I do in my 48 Anglia this setup works great! It's the only place to mount the alt. that works. The hardware comes anodized, which don't match the bracket. I had to change that out...used stainless.[...]
Pros:
  • Heavy duty
  • Easy To Install
  • Nice Finish
Yes, I recommend this product.

The one I got ended up between the 2 pullys, so it had to be shimmed out to match the out pully.

Is this compatible with the Zip water pump riser? I currently have this bracket, and really like it. However, due to heating issues, I need to install a Zip water pump riser. Will these two fit side by side, or are they not compatible?

The Zip riser has the alternator mounting ears on the drivers side and on the passenger the boss and brackets for an A/C if desired. To get the bracket you have work with the Zip riser you would likely have to remove the alternator mount from the riser. To compare to your alternator location the riser alternator mount lines up with the centerline of the two water pump bolts.

Is it possible to flip around this bracket and mount it on the front of the passenger side head? Similar to stock alternator location.

This billet alternator bracket is designed for attachment to the drivers side head. If mounting holes are the same in passenger side head it could be installed on that side. Spacing front to rear will be different and require the appropriate spacing for belt alignment.
