372or 416 and why

no its not a bracket car I go to the 1/8 track for time to time now.may would go more often if the car was a little faster than now ..just really disapp. with the way it was running..7.70/89.9mph 1.77/60 but I have talked with alot of people Bobby being the one that got me to understand why the car wasnt 60 and running better..now the motor apart and have the chance to up grade.so I thought I would ask to see the good the bad or what ever...now as far as to what the car is used for mostly would be a few trips to the local store sometimes 5miles then to the local drag 1/8 a few times..so more street than race....
