That should land you solidly into the mid to low 10's for sure!!!...


Local guy here that has a 632 twin turbo 57 Chevy has siumilar issues. Car runs real storng back half numbers, but he has been 3 years trying to work out converters, gears and turbos. Good running, good working car, but never runs a representative ET based on the MPH. Its just tricky hard to get them to ET early in the run. he has a big inch motor too, but is currently downsizing the motor to try a different approach I believe.

I wish you could have maximized the screw set up, as there was a lot more in that package, just never got to reach that goal I think.

The data recorder will be your friend here.
