C4 A/C Blower in a C3 upgrade

Did the pigtail connector recommended on page 1 fit the blower?

I used the NAPA connector, but I believe the GM part# is the same .

Has anybody tried to do this swap into a non A/C car?

Not me, but my old '72 vette squirrel cage and motor assy went into a old camper/motor home with no sweat, increasing the air flow a decent amount....it has aftermarket a/c on it...so the heater/blower fit fine...

...all those blowers I have seen were identical in the 70's....

Yes. Same for both AC and non cars.

(And yes Gene, I will upgrade to a #10 ground wire at that time).

I read through the posts, maybe I missed the answer. If I want to get a C4 fan for my 70, do I order the 1580182?

Thanks

Also, Can someone recommend a compressor for me? I'm using a Serpentine drive on my BB. (GMPP Serpentine for a SB with adapter plates.) It will accomodate an R4, but I'd like to put in a modern aluminum compressor (Sanden, Niponso...) Recommendation for a compressor that'll mount up in place of an R4. Thanks again.

I don't think there is an adapter for a Sanden style/R4 conversion and you will have clearance problems with the head. Even though the Sanden is smaller, it is longer than the R4.

This is a picture of my R4 on a BB.

Some reason I can't download the spacer diagram

There are two .pdf files. One is dimensioned and the other is to scale (so that you can print it and use as a template).

Gene are you taking parts of the vette to put on the old motor home ?
