Just got done with the sb 408 upgrades. I changed heads/cam/torque converter. the heads are ootb indybrocks, 1.5/1.6 rockers. cam is Comp solid roller 248/254 @ .50", 616/582 lift. tq is a reworked dynamic 9.5 with 4100 stall. Just got it all up and running, but seems like carb problems(currently has a 750 mighty demon). runs real rich, and has idle problems. is the carb too small???? what are you guys using for sb 408 strokers??? trying to get this ready for mopars at the strip.
