OK gas mileage update. We built a low dollar 388 small block with vortec heads and a performer intake with Qjet. 10.3 compression flat tops and a 350/327 cam, ramhorn exhaust. Gas mileage went up about 30-50%. I'm sure the torque and efficiency of the heads made a big difference. Truck weighs about 4200. The reason I say low dollar, we used swap meet heads, ebay intake, speedway parts, $200 long block. Wish I had a 2200 stall and maybe 3.73 gears but pretty happy with it. Thinking about maybe summit headers next summer.
I am now running a 96 chevy starter with 1000 amp Interstate battery and Ford LTD starter relay on the inner fender. Starts on demand now. Dual tanks, (3 port switch) electric pump.
