Hey maybe someone can help me out here...
I bought an inline 6 from an 60's Chevelle and had to overhaul it. According to the engine code it's a 194, but also a counter exchange engine. When I measured the cylinder bore, it's the same as a Chevy 230 ?? Anyways, I replaced the rod, main bearings, piston rings, lifters, valve springs, and camshaft with a performance cam. Well today I got it all back together and fired it up for the first time after having it tore apart for a couple of months. The engine ran and sounded good, but had a slightly rough idle which I believe is cam related. Does anyone know if replacing the 1 bbl carb with a 2 bbl carb will help with this problem? Other than that, the engine runs good and doesn't smoke at all.
