Hey guys,
I just finished my 13B swap into a 1990 B-2200 pickup. I started with a S4 6 port motor, ported with Pineapple Racing's templates on the fuel and exhaust. Running Racing Beats Holley, intake manifold, header, and 2 1/2" pipe all the way back with Magnaflow strait through muffs. Motor starts and idles fine once I tuned the idle mixture, but I am not making any power down the road. It is responding likes it's running lean. Does anyone have experience with this? Have any idea what jet sizes I should start to tune from?
