3600lb truck, 4.10 gears, 28" tires, 6.0 lq4 shortblock, l92 heads/intake, long tube 1.75" headers/no cats, factory stall. I'm having it dyno tuned next week and I want to get my moneys worth . I want as much tq/hp as possible using the factory stall and in the 1500-6500 rpm range. It has a 21/218 116 lsa cam now.
