msd, demon,exhaust
 

i have 502s w/victor jr intakes,rec port heads, roller cams, rockers , 750 holleys, im adding a complete msd ign system, sea demon 850cfm, revolution marine exhaust. whats to be expected, more rpm? more speed?
liter pockets? the motors are less than 75hrs old and have a choppie idle specs are unknown:confused:

My guess would be minimal increase in speed. If you have stock exhuast you should see better mid range and the msd and new carb should help idle if you set it up right. I used the mighty demon carb and so far so good.
