for a bracket car they are good, although there are newer grinds that will run w/ them. You need to have at least 10:1 to run them, 3800 stall and 3.91's. they like good heads and a free=flowing exhaust. You can build an easy low 12 second b-body w/ that cam, 10:1 440, headers some head work, intake and 750DP. Not much to it.
