Re: strange cooling

I have a v7 compressor for a c5 corvette coming with a v belt clutch. Now I just have to build all new bracketts. I used to have a small structural steel shop so manipulating steel I understand.

Re: strange cooling

But what are they for? Back in the quarter midget days we used to do everything possible to squeeze a little more power out of a, I think it was a continental single cylinder. One of the questionable tricks was to support the camshaft lobe in a polished cradle and smack the top of the lobe with a bi...

Re: strange cooling

About the forum, there was an e mail that I glanced at that seemed to be alluding to the fact that this is an a/c forum and not a power train forum. I will have to dig through the e mails and look at it more carefully to see if I misread it. Not a major issue I just don't want to ruffle someones fea...

Re: strange cooling

The moderators seem to think that we have gotten off topic and rightly so. So to get back on topic the C-5 Corvette, 97-04, do they all have the V7 compressor? There seems to be some confusion in cyberspace about that. If the C-5 compressor is a V7 the mounting on it looks like it will work well wit...

Re: strange cooling

intake 268 / 208 @ .050. IO 22 BTDC closes 66 ABDC exhaust 270 / 214 @ .050 EO 67 BBDC closes 23 ATDC Cam is dialed in straight up The most logical trans change would be a 200R4, supposedly it will bolt in without an adapter. Problem is that by the time I get it in I will have spent 1/3 to 1/2 of wh...

Re: strange cooling

Finally getting back to the Pontiac, had a 3" cast iron waste line inside a kitchen wall split open. I had to tear the kitchen apart to get to it. It had about a three foot long longitudinal crack that separated about 3/8". I have never seen anything like it and none of my contractor frien...

Re: strange cooling

I am not sure what kind of an anomaly you had with the 2bbl 400 but you are the only person I have heard that had anything noteworthy to say about Pontiac fuel economy. If you happen to know where that '70 Catalina is I would like to buy the engine and trans out of it. Of course there is also the is...

Re: strange cooling

Engine is a 389 with a very short camshaft. Problem is that there are no aftermarket parts for pre '65 Pontiacs. If I could find a 4 barrel intake and use an a of b series AFB I might be able to squeeze a couple more mpg out of it but it needs premium fuel because of the compression ratio. The origi...

Re: strange cooling

I went back and read the entire thread, sort of like job notes. I realized that I had the original weird problem where the auxiliary fan was being wind driven and generating enough current to keep the clutch engaged That got me chasing all the strange rabbit trails ultimately reaching the point wher...

Re: strange cooling

I put in the .072 tube and there is little change. The problem with this Pontiac is that I need 40 degree nozzle air at full blower just to maintain a livable cabin temperature in 100+ degree air. Nothing is insulated, a dark blue convertible top and untreated glass. Driving on a sunny day you can f...
