[AROWHED]

For now I have a 455 with 1971 '96' heads, so I have all bolt options available. Hopefully soon will be changing to a new engine with E-heads, but should still be able to bolt anywhere.

[Ollie]

Yes, The E heads have all the bolt options as the stock heads.
I would recommend the Vintage Air bracket
141001PPA. That is the one I am fabricating The adapter for.

Do you have a PN. or post a photo of the bracket

I'll look. If I recall correctly my bracket had a provision for one bolt boss on the side of the head but, it didn't line up with anything on my head, '67, and it was optional to use it, it's just an extra fastener point. It’s definitely not the bracket shown using both side bosses.

Here's mine 141001-PPA.

[Ollie]

I see what you are talking about.
Yes the Bracket is changed. Look at the small print in the border at the bottom of the page. in the link you posted the revision is rev C 5/25/10.
In the link I posted it is Rev A 2/9/05.
I do have an early bracket.
This is a problem is the modification I have requires the compressor to be moved forward 1 5/8" to line up with the crank and water pump serpentine pulleys.

[Ollie]

Vintage Air redesigned the compressor bracket so it can be used on both early and late heads.
Have ordered the revised compressor bracket and will revise the adapter.

VINTAGE AIR SANDEN COMPRESSOR BRACKET EARLY DESIGN.
SANDEN AIR CONDITIONING COMPRESSOR WITH SERPENTINE BELT.
Anyone following this thread knows I am using a Sanden AC Compressor with jimmo’s serpentine belt conversion. The following is my findings and recommendations.
1. There are two Vintage Air, Sanden to Pontiac Engine brackets. An early version linked at page 2 post #38 and a later version linked at page 11 post 204.
Either bracket can be used in the serpentine belt modification. This first post will be directed to using the early bracket. The early bracket bolts to the head, using the two cast in bolt bosses on the side of the head, and one long bolt with spacer on the front of the head.

Purchase a length of steel flat bar stock 1 ¼ inch wide ¼ inch thick. This modification requires a 9 inch length.
Here in the Seattle area, I purchased this at Tacoma Screw Products, in a 3 ft. length which is the shortest length they have.
McMaster Carr or Granger supply or any industrial supply might also have this bar stock.
http://i361.photobucket.com/albums/o...Extensiotn.jpg
This is a CAD drawing of the spacer to move the early Vintage Air bracket forward 1.625 inches.
Fabricate this spacer the Sanden compressor will be in correct alignment with the serpentine belt.
This spacer requires two ¼ inch spacers, one each between the spacer and head bolt boss.
These ¼” spacer can be fabricated from the bar stock purchased to fabricate the bracket spacer or purchased from.
http://i361.photobucket.com/albums/o...T/IMG_1376.jpg
http://www.aluminumspacers.com/
All spacers used in this modification can be purchased here as well.
When taking any measurement insure the measurement is taken from the flat machined surface of the head.
I purchased a 1ft length of the perforated angle to use in prototyping the spacer. To allow inserting the bolts, the holes and slots had to be enlarged slightly with a rat tail file.
http://i361.photobucket.com/albums/o...ypeBracket.jpg
Number 1Hole is the Forward bolt boss on the side of the head; Hole 2 is the back bolt boss on side of head.
Hole 3 is the forward bolt hole on the Sanden compressor bracket. Hole 4 is the back end hole on the Sanden compressor bracket. Hole 5 is an extra bolt hole drilled in both the Spacer bar and the Sanden compressor bracket. Drill this hole 2” forward of the existing forward bolt hole in the Sanden compressor bracket.

After the compressor bracket is fabricated a 1” and a 5/8” spacer will need to be added to the front bolt.
When installing longer bolts. Purchase bolts with enough length to provide a minim of ½” up to ¾” threads into the head.

On page 8 post #154, Jimmo shows a solid link for tensioner-made from 1” bar stock. That bolted to the belt tensioner and the R4 compressor bracket spacer. Doing some research I found that March Performance lists a large selection of turn buckles.
March Performance lists the turn buckle in various lengths from 3 5/8” to 18”.

This is my idea of connecting the serpentine tensioner. Of course I need a longer turn buckle, but this gives you the idea. I don’t think using the existing bolt will work as the angle is too steep and the turn buckle wanted to interfere with the belt tensioner. The distance from the belt tensioner to the compressor bracket is about 7 ¾”. So a turn buckle of the correct length would need to be purchased and trial fitted to determine the correct position for the bolt.
I purchased a Goodyear Gatorback serpentine belt to check the pulley alignment.

LATE SANDEN COMPRESSOR BRACKET
Vintage Air redesigned the Sanden AC compressor to Pontiac Engine bracket. If you have this bracket or if you purchase one now this is the bracket you will receive.

As you can see this bracket mounts to three bolt holes on the front of the cylinder head and the forward bolt boss on the side of the head, making it compatible with both early and late heads. Mounting this bracket flush on the head or even off set 0.608 using the spacers and three bolts provided with the Vintage Air bracket kit will be OK. Moving the bracket forward 1 5/8” required for the serpentine belt modification using only three bolts. The needle on my concern meter started twitching, as I thought about the stability on this arrangement. Calling upon knowledge gained fabricating the spacer extension for the early compressor bracket. I designed an extension bracket for this late compressor bracket, fabricated from the same 1 ¼” by ¼” steel flat bar stock. http://i361.photobucket.com/albums/o...Extensiotn.jpg
Moving the bracket forward 1 5/8” requires the use of a 2 ½” bolts. However a 2 ½” bolt cannot be inserted in the top bolt hole because of the closeness of the forward angle.
http://i361.photobucket.com/albums/o...T/IMG_1390.jpg
This requires the use of 3” studs.
http://i361.photobucket.com/albums/o...T/IMG_1398.jpg
They are exhaust manifold studs, 3/8 – 16 X 3”.I purchased at a local Auto exhaust specialty shop.
I also found them at auto parts stores.
If the studs have the hex end do not get them, the hex end is included in the overall length, when installed they are too short.
http://i361.photobucket.com/albums/o...T/IMG_1399.jpg
When installing the studs, be aware the bottom hole is open into the head bolt hole. Installing the stud on an engine with the head bolts in place. The threads should be clean enough to, screw the stud in by hand, apply Loctite on the threads, screw the stud in by hand until it stops against the head bolt and back off about 1 turn. If installing the studs on a head that is not mounted on an engine, thread the stud in by hand watching down the head bolt hole, stopping before the stud protrudes into the head bolt hole.
Before installing the compressor bracket. There is a slight interference with the end of the compressor bracket and the head bolt boss.

Trim off ½” on the bracket end.

Newbie here, just read the thread. Great work jimmo and ollie, any updates?

[Ollie]

Yes, my system with the Sanden AC compressor is finished. Working on the up date. hopefully will post the up date over the week end.

[JC455]

Any updates?

[Ollie]

How's this for a teaser.
The DIY Junkyard serpentine belt with Sanden AC compressor installation is complete.
working on step by step instructions with photos.

[Fishin2Deep4U]

Looks good ollie.

Did ya male a change or two to the idler arrangement? Looks much more solid and definitely addresses my other concerns. Maybe I'll just swap to the 11 bolt pump setup now as the manifold is off.

Yes,
Drilled the idler bolt holes to 3/8" and mounted the idler on the 3/8" water pump using bolt. Using a 5 1/2"
bolt and the 1" and 5/8" spacers.
It is more solid than using the smaller 5/16". With the belt under tension the deflection can be seen.
I would recommend swapping the timing cover to the 11 bolt especially I see you are running a 455 with 6x-8 heads.
Use a late 11 bolt cover with out the timing tab.

[JC455]

Coil packs? LS1 oil filler? You and I must share a brain- lol!

[Ollie]

These are the truck coils.

[russosborne]

Jimmo,
are you still selling the kit for this?
I might just want to buy it instead of piecing it together.
Thanks,
Russ

[Ollie]

Jimmo's last activity was on Jan.9th
He got hit pretty hard by Sandy I hope
He is OK.

[russosborne]

Ouch.
Hope he is ok also.
Thanks,

Hi guys, all is well here, just been really busy. I have been meaning to post an update but just havent had time.
During a drive around my neighborhood I did have my first issue with the serp system. The front rib of the belt separated from the other 5 ribs behind it. I pulled over and cut away the bad portion, reinstalled it and drove home.
Not sure what caused it but many posts back someone chimed in with info on foriegn pulley pitch vs domestic pulley pitch so I started there. I found an alternator pulley from an 89 el dorado with a 4.5 ltr to replace the volkswagon pulley. This needed to be spaced a little more but still has enough thread for the nut to go all the way on.

Not sure if the pic does justice but the vw pulley has deeper grooves and taller peeks.
I hope this was the problem and I nail it on the first try but if not I will keep diggin till its solved. If anyone else has any theories please chime in.
My thinking is that the taller points on the vw pulley were bottoming out in the grooves of the belt and eventually cut through. I wish I recorded the mileage but Im guessin it happened around 2000-2500 miles on the belt.

This may not have been the problem but I think its the most obvious place to start. Ill keep yas posted but I wont be putting any miles on until the salt is off the roads around here.

Oh and thanks for the concern guys, I held up fine here in the storm but my family on the nj coast got a lil beat up. All is good now though.

Also, Russ, I do have a bunch of stuff I put away in my basement Ill have to check to see what I got. You can PM me with anything you need but you might wanna wait to see how my new alt pulley works out hahaha.
