Maybe this question has been asked before and i remember hearing that vintage motors will leak because of old sealing technology. If it is safe to use in vintage motors, i was thinking of using it in my 57 Pontiac 261 inline six and my 74 Chev 400 V-8. I am thinking that maybe the only real concern is the pos...

Had the car out last week for a quick jaunt and all was going well. Headed home and something didnt seem just quite right. Checked the gauges and everything was good, until the oil pressure tanked and the angry little man in the bottom end started smashing away with the ball peen hammer. Shut it down and p...

I picked this up with a bunch of other stuff the other day. The previous owner was not sure of it originality other than it was from a mid sixties car. I could not find a date # or anything that can tell me what it is. I am asking anyone out there that can ID this carb. Thanks

Just received an order from Jegs, and in the flyer that came with the order was a listing for a Spectre dual inlet ram air box. Obviously offshore, but all for $167 USD it looks to be an economical ram air system. Paint the housing black and it would look pretty good. Even includes a reusable filter. They m...

Is Eastwood the only company that sells black radiator paint? I don't want to spray my nice new aluminum rad with regular paint because I've been told that's a great way to reduce it's efficiency. Anyone seen any other place to buy specific radiator paint?
