If I used that 4.0lbs to cube I'd have to add 400lbs to the car
.
We are trying to find a class that we can fit that is in the low 7 range. We will probably run PRO 7.0 or slow it down for NE1 in the Heritage series. Hoping to find something for the regional and national events.
We have been running with a top fuel family driving and wrenching on the dragster and wrenching on the Funny car, yes speed costs money and sometimes lots of it.
We are a few months away from running our blown 445 cube aluminum Buick in the car. A lot of the parts are custom made but we have many parts that are Ford, Chrysler and Chevy high end race parts to keep prices down and make availability better. That engine is definitely a cubic dollar engine.
Thanks for the info
John
