So i shut the car down. iam out of ideas. Stock 350 with a dual dual plane weiand intake, 600 holly, headers, HEI, MSD 8mm wires, and dual exhaust with 40 series flowmaster. thanks
sounds like the hose was loose. shouldn't have blown off if the motor did run hot. i'd check the valve adj., and be sure the carb. is adj. properly. check the plug and comp. on that cylinder, compared to another cylinder and see if you can find something dif.
