84 GMC Sierra 15 305-700R4 questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**RPOZ11** · 07-03-2004, 07:26 PM

Hi! Just bought this truck & Im dialing in the little things. It is a Gov't ordered fleet truck, has the 305, 700R4 set-up and unfrotunately the under dash computer for the emissions and the carb & distributor.
Anybody here have any knowledge dealing with these, getting more performance out of the 305 and still stay within the smog laws guidelines? Im in California, so Ill have to stay within the limits. I did look up cams, seems CompCams has a C.A.R.B cam, but I would like to get more out of the heads and intake for better all around performance.
Any thoughts here...??
Thanx!
