have recently converted my 86 chev 3/4 ton 4x4 350 engine over to propane and would like some information on tuning the ignition and mixer. i had build the engine with specs that i thought would be good for propane. block is bored 30over decked and all the other goodies camshaft is a comp cams extreme 4x4 designed for low-mid performance intake is edelbrock performer heads are world products 67cc chamber high compression heads with 202 160 valves. approx 10.5 -1 compression ration. im also running comp cams 1.6ratio roller rockers for increased lift headers and good dual exhaust. on gas this engine seemed very strong but now on propane it seems to be lacking. any suggestions or recommendations on tuning. thanks
