I have been having a lot of trouble out of my holley double pumper, since I bought the car last year. It has a oversized cam and I don't know any of the engine spec's. My intake is the old Torker 340 and the car needs a stall converter really if i keep running the current setup. I have no low end torque. I keep getting gas in the oil from the Holley its old and been rebuilt several times. A good buddy of mine gave me a New rebuilt from Chrysler thermoquad, it's for a 1977 400 HP engine. I can pick up a intake from another buddy, he has a stock 340 cast iron intake 71 casting he also has a wiand spread bore he'd sell me, I'm leaning toward the original cast iron because I can use the choke, what do y'all guys think, should I just buy a new holley or switch to a dual plane and use the thermoquad and maybe gain a little low end torque?
