I would look at fuel pressure number #1. If it runs lean, you are going to hurt something. Yeah, it could be blowing out spark if the plugs are gapped to big but, make SURE it has fuel pressure.

Do you even have any kind of AFR gauge on it somewhere? It's a good idea to run a wideband on a blown setup.

ive got my autolite 24's gapped at .032 and it fixed my problem, car was cutting out really bad at high rpm's. A coil will help with output but an ignition box will be well worth the money and is needed.
