Hey did you know that Pontiac only put the chrome covers on the 67 2+2 cars. All other 67 427s and other years were painted. Someone was questioning this awhile back... Hey how do you enlarge this image ?? -- Edited by Elroy on Thursday 9th of April 2009 12:39:03 AM

So, we all know of the "campaign-recall" GM had on the engine mounts in these cars for the small blocks. I have installed these kits in all my small block cars but I have never seen a kit for a big block untill I picked up this '67 Grande this summer that had a 396ci. It had these cables still in pl...

A friend was over a few days ago and we ended up talking about cooling. He runs a small garage in a town close by, and is a bonified car guy. I told him I now have an all aluminum rad, and that I'd like to eventually run some electric fans. He took a look at the rad and said right now they have a 99' Neon that is too...

What size was the 69' "B" body SB cooling fan? 250HP. 17 or 18? I've misplaced my original one. And is it advisible to go with a clutch setup or just a straight fan. Cheers, Mark.

Finally started to work towards installation of the new Autogear M 20. I installed my original shifter to make sure it fits. Needed shims behind the shifter plate 3/16ths. Everything then worked the same as previously.

(off e-bay) He sent the metal holder for them, and the rod, going through firewall, and swivel, and clip, and the brake switch, and rubber pedal stop Texas stuff, looks 6 months old...

After about 150 miles of trouble free driving in the last couple of weeks, the Laurentian started to run hot last night. I drove about 20 miles without a problem and while waiting at a drive thru for ice cream for my son and I, the gauge climed from 1/2 to 3/4. I figured once I got moving it would calm down. No...

I need to know if the A/C cooler from a 70 Bonneville will fit into a 70 GTO. The rad supports are different, but they may use the same brackets? Also is there a place in Canada that carries A/C coolers or lines if it won't fit? Thanks

Here is a shot of the engine bay of "Project Beaumont El Camino". Can anyone ID that air cleaner? It looks like some of your BBC's but it has a chrome lid, no flappers on the spouts either.

I have the chance to buy a Ram-Jet 350 former crate engine with about 70K on it. It seems this particular block is supposed to be a relatively easy switch to older cars, literally drop it in and turn the key. Has anyone done or heard of one of these conversions? Any specific issues to look for? Thanks

I been wondering about this apparitus, located on the driver side inner fender well, since I bought my car. I can see that it's not hooked up to a vacuum source. Is it an old style pump of some sort or maybe cruise control ???
