MSD....worth it?
Reply #5 –
msd is a good upgrade.
an example we have been working on a 79 camaro with a 468 bbc car was fouling plugs out. swapped in a 6 box and had to jet it up 10 jet sizes.
carbed cars will benefit the most from it.
fuel injection also benifits with better milage, easier starting,better throttle responce.
and with high boost levels it helps keep the spark from blowing out.
