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.




I know of a few that have had problems with Demons
specially on idle... I believe a 750 is too small
for your 408.... I run a 1050 on my 405ci... but
RPM has something to do with the carb selection
