what outcome should i expect from either? i want quick accel but nothing thats gonna spin tires thru the whole run. a local ex-TD street racer (in the 80s) is telling me to use the .48 and get rid of the .63 if i want the best overall power and accel. i have a 2.5 CB bottom and a t2 top end and putting on a 50 trim hybrid turbonetics. thanks
