SBC alternator relocation

I'm just looking for all ideas to relocate an alternator with a short pump. I changed over from a serpantine setup from an '86 Monte Carlo to the V belt. I did it just to look a little older.

instead of reinventing the wheel, and I understand wanting to fab it in house. Why not just use those as ideas, then build from there. I only mention this because, Alternators and under the hood restate are a tricky and deceiving play ground.

Use the ideas but fab your own brackets is all I am saying .

I've done this several times, and never found it to be anything tricky. It's pretty simple to find a location I like, put a belt on the pulleys, and then just line the alternator up wherever. I just bolt aa piece of steel to a point on the block, head, or intake, and then tack weld the bracket together. Once it's tacked I pull it all off and weld it solid, then paint and reinstall. Just had to do this on my present Austin project to relocate the alt. to driver's side short pump, from pass. side long pump.

I'll have to get a decent one today. The only pic of that side of the engine doesn't show the mount, just the alternator.


Here's another trick that I used on that mount. For an adjusting arm I used 3/8" running thread. Simply bolted a "L" bracket to the block and the alternator, then bend it to fit and double nut each end. Loosen one nut at the alternator and turn the other to adj. Then tighten the other nut against it to secure the alt. I covered the threads with flexible chrome wire cover, but a braided flex hose like a sink faucett feed line also works well.

Make sure that the alternator will still have some airflow to coll it off wherever you mount it.

Here's a bracket i made to mount a 10P13E AC compressor outboard of the right valvecover, mounts to the front of the head using the existing 3 boltholes. The design could easily could also use to mount an alt...



The basic plates are made from 1/8", the hole punched reinforcement is 14gua, with a slotted 1/4x1" aluminum adjuster.
Very lightweight and rigid.

My alternator has plenty of cooling! It's sitting inside the driver's side fender, since the engine bay is so narrow that anything outside the valve covers is not nder the hood!

Here's somewhat of a pic of the alt brkt on my street car...



The main bracket you can barely see behind the alt is made of 3/4 x 1" solid steel w/ a 3/4"od tube welded at the bottom (kind of a inverted "T").

The black bracket above it that you see is just the motor plate.

Here's a pic of the alternator bracket on my Austin gasser:

I cut a piece of heavy wall tubing to go over the front header bolt, then built an L shaped plate to mount on the front of the head. Welded in a gusset between the two to tie them together. Then I bolted the alt. onto the plate using another long piece of the heavy tubing and tacked that to the bracket. Cut a gusset to support the tubing to the bracket and tacked it in too.
After that I removed the bracket and welded everything solid, then painted it black and bolted it all back together. Used a GM alt. converted to 1 wire with a jumper and it works great.
