have a 289...just went from a 2bl motocraft carb to a edelbrock 500...got it out of the shop after it was put on and ran fine for a day. The next day i went and got the 14 by 3 air cleaner by edelbrock and started having bad exaust problems. The exaust is white and there is way WAY to much comin out. Also, my temp went way up and was burnin up all the coolant i kept puttin in there. I just installed a new thermostat and my cooling systems been workin fine till i got this new carb (heard that the gas can start to boil if to hot)....I noticed smoke (or steam) comin from out of the cap that screws onto the valve cover. Also, when i checked my oil all there was in there was foam and i couldnt get an acurate reading of the oil level. Im going intall the banjo adaptor thing that came with the edelbrock air cleaner and connect a hose from that to cap on the valve cover like my stock air cleaner was....is that the problem? do i need to be runnin my carb leaner? or am i having vaccum issues? i have hi-po manifolds and flowies so i know that my exaust is fine...any advice would help! oh and i do have a timing vaccum....if that matters....cuz i know theres another type of vaccum.
