Hi guys, I'm new here, just bought my first true stovebolt... i used to have a '64 chevy II with a stock 194, but i just bought a '62 chevy LWB fleetside with a 235 (i assume, unless a 261 was available in '62, how can you tell?) it has a Edelbrock 2X1 intake, with 2 Rochester B's and a split header, dont know the brand. I'm having some issues with it, as far as a stumble off idle, and it runs rough while holding speed under 50 mph. any thoughts?
