Is this a drag race only build or a street and strip build? If drag race only I would install the .620 and advance it so it is in from 3 to 6 degrees advanced on the ILC Big motors love big camshafts Who ground that .620 cam and what LSA is it ground on ?
Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
