Shift point and gear ratio Rb race Engine ?

mid 9's but the hotrod did have a major valve spring problem I didn't discover until a few years after I supercharged it. with that addition it's got 4.10's and 31's. now that problem is gone and everything under the sun and stars showed it's ugly head. I don't have enough space to type all that. i'm getting a handle on all of them. once they are all ironed out i'm looking for a 5.0 in the 1/8th with the 3500lbs demon.
