Street Hemi Grind cam is a real good one to use.Still using the old one that Dad bought in 1972 in the 383 Road Runner,only cam we ran in that car and went 12.26 in Atlanta with the usual bolt ons and 4.88's with a 4-speed.After I got the car,I put in 3.23's and used the OEM 585 cfm Holley and stock 666 intake and the car ran very well with it.I'm going to stil use the same cam when I finish restoring the car later this year.
