Hot 318

Well guys I tracked down the problem finally. It seems that the 4 bbl intake is equipped with a heat riser choke system and if you use the electric choke option on the carberator you need to block of these ports in the intake using a non-egr and non-heat riser gasket kit. The hot exhaust flows through this port and with no place to go heats up the atomized fuel so much that it evaporates before it hits the cylinders. If you are upgrading the 2 LA egr equiped 318 and do not want to use the egr, use the 4 bbl intake non-egr from Edlebrock. If you have the 4 bbl with egr than you will need to install the 4 bbl intake gaskets that block off this port. Happy motoring.
