I recently had my block stroked to a 331 & got a cam, see sig below for rest, my previous #'s were 355 RWHP what is the stock ignition rated to ? I do have a msd boost timing master "it's not an ignition" but supposable fattens the spark allittle bit, my question is do I need to upgrade my stock ignition now or ?

stock coil is good for 500hp put out 30k volts....and when mated with a ignition box can go to 600hp........so the answer would be dont be like me leave it stock....
89-93 systems actually put out 38kV @ 90 millijoules. It's a good system for any N/A streetable car.
If your running less than ~12# boost, it's still good. More spark energy never hurts though and as boost pressure goes up, it is harder for the spark to jump the gap.
