Greetings again my friend:

Here’s the photos I took of my failed installation of the Sanden 508 Compressor, and the upgrade brackets sold by Classic Industries.

This might fit Mopar 383’s with stock heads, clearly from the photos, no way - no how will those AC Brackets bolt up to a 383 with Edelbrock heads.

Is there a logical answer for this equation, or am I doing without AC?

Thanks in advance - Doug White

If you’re saying that that bolt is too long than cut it to fit.

Probably the heads are too long at the front pushing the brackets too far forward .

Yes - that C.I. / AC bracket set up isn’t compatible with those Edelbrock heads, as it is. It’s going to need a little finesse, to make it all fit.

I don't see any new brackets in your pics.
Edelbrock heads like most aluminum heads were not designed with a/c fit in mind.

Viola…..it’s in there…..

 

[moparleo]

That's much better.
Is the problem on top with adjusting the belts ?
Can we get a better picture from a little ways back to see more of the front of the engine. You are there, we aren't.

Yes, I ran into a belt adjustment issue with that chrome C.I. Alternator. The head won’t allow for the full adjustment of the alternator - but it’s close. I’m going to try a little shorter belt, and see if that might be a viable solution. I’ve still got to make final fit adjustments to the AC bracket jewelry, after that’s put to bed
I’m really surprised nobody’s ever tried this before - this forum has a knowledge base that’s second to none.

Remember that with a dual belt application, the belts should be a "matched set". That is because belts will vary in their length and this will cause squealing as the belts are actually spinning at slightly different speeds.
V-belt Matching
Here is a posting from another forum "

matched sets are still available, most parts store dummies have no clue what a matched set means,....when a belt is made, it starts life as a long tube that gets turned (cut) in to the desired V rating (width and profile) numbers are stenciled along the belt in a progressive series along the width, ...example 33345 and 33346 are matched, 33345 and 34478 are not, it was cut further down the tube, which may be smaller or wider in diameter,....the BS line that all belt are now built to exacting standards is BS,....find a parts store that can supply your request

May be the case with some but not with Gates.Just went through the same thing.
What I was told:

All of our v-belts a formed ground (cut) and are within 1/,1000 of inch tolerance from each other. When the dealer told you all belts are matched, he was telling the truth. With that said, a few years ago we changed the design of the inside cogs of the belts. Please see if the cogs match each other. You will also see a code in red ink on the belt (example:238SS). That tells the run date and location. If those numbers are close or the same, that means the belts were mfg on the same spool.

Just an FYI for you guys out there working on older, v-belt a/c with double belt system and are having noise issues when turning on the a/c.

That is great info, that the tolerances are now what they should have always been. Somebody had a matched set listed for four times the price, just because they were matched set.

I went through the belt thing when I converted to Sanden with dual pulley.
Bought 4 belts at local auto store, mixed and matched until I found 2 that worked together and returned the other 2

Only those that can see the invisible, can do the impossible…..

That Sanden AC unit now fits my 383, with those Edelbrock heads. Looking at the service manual, everything else lined up as originally designed. Snug, but functional…..
