My C30 dually has a 350 stock except for a pair of heads off a 267cid, I installed them despite the small valves because I live at 6.600 feet of altitude and the extra CR is very welcome, it performs nice on regular gas, but since I use this truck to haul about 7.000 pounds, I would like to get more torque out of the motor, I have an Edelbrock Torquer II manifold laying around, how would this engine perform with it? I also have a 0-1850 600 cfm holley to complement, the truck has 4.56 rear end and a TH400 tranny, dual 7.50 x 16 tires, the motor very seldom sees revs above 4.000 and the throttle goes WOT going uphill fully loaded in 2nd gear.
please make sugestions to improve it.
thanks,
Augusto.
