well after a little grinding, a little milling, a little filing, a little cursing, and a little nashing of teeth i have got my headers, clifford intake and edelbrock 500 installed. i fired it up and it started great. my problem is after it ran a couple of minutes a kind of hazy fog was coming from engine bay. i wonder if it was paint burning off headers or if it was a rich fuel mixture from a leak. this is a rebuilt 292 and when i took off the stock manifolds i used for startup it had a oily texture to the inside of the intake. mabey what i saw was a oil/ gas mix. i have only drove this a couple of times since startup with the stock intake. it didn't run like it had a vac leak had great response. i have been working on the linkage all this time. also i hooked up the pcv line to front of carb like instructions say. i pluged the manifold fitting was thinking of installing a perminent vac gauge in dash has anyone else done this? mabey i just need to lean down the air screws. any suggestions? thanks, hoggyrubber.
