Trying do decide which cam to run in my 383, it's in the shop now, '71 383 all stock bottom with hypereutectic pistons .030 over with stock compression, only headwork done will be port-matching, I will use the stock intakes/exhausts/carb. I'm looking for a bigger cam than stock but not a street/strip type either. Heard good things about the Comp XE285 HL Cam 285/297* gross duration or 241/247* @ 0.050
The lift is 0.581 intake and exhaust with 1.6:1 rockers, but as I have power steering/brakes, that cam is probably way too much with no vacuum. Perhaps the HE275 HL would be more practical with better vacuum, but would like other opinions. Also I read here on the board that there is another brand that some of you swear by but I can't remember which one (I think Chryco suggested one once). Any suggestions would be appreciated. BTW it's a 4spd with 3:55's. Thanks! Greg.
