Vectric forum .625 rpm6/13/2023 ![]() But, I am somewhat tempted to throw some 12:1 pistons in it while I'm in there. A dual plain intake will only flow good to about 6500 rpm's and if your converter is 6000 that's only a 500 rpm difference if your converter stalls that high. I'm on the fence.i'm going to at least re-reing it and have the heads milled down a bit (it there's room). I agree with John on the converter being to big. my 'lil 396 is showing 20 - 30 % leakage and I have 118cc combustion chamber heads. I'm probably going to wait a bit on making converter changes. All my friends run dragsters or 8 second door cars, so I probably have the smallest converter. Unfortunately I'm passed my time period to get my stall moved, but I'm sure I can pay to have it changed. I decided to call doug herbert and see what they recommended after giving them the run down the guy said, "what's the catch?" Then went on to say that he was amazed that the car made it down the track. The cam was way off to be running on motor alone. Anywhoo, i bought a converter bases off what we thought it would run. ![]() I bought the motor used from a guy who bought it in a ride.but then he sold the ride less motor. When we sent the info into trans specialties we used the cam info it came with the motor. ![]() Right now I shift at 6200 and it just seems like it's goin dead before I get there, was thinking I might be dropping rpms after I shift to where it would hit after my torque curve.
