I pulled all the emission and pollution junk off my 305 engine and was wondering if now I need to run a different heat range spark plug? Anyone know? Thanks Rob

What year vehicle? What kind of car or truck?

The engine came out of a 1986 carborated van.I put it in my 1976 camaro. Also on the distributor it has a pigtail of wires that comes out of the back of it. these are not the wires that plug into the cap but for something else. Does anyone know what these go to? Would I be better off buying a distributor without these wires or will this one work with nothing hooked up to them? I would appreciate any advise. Thanks, Rob

R45ts plugs with a .045 gap would probaly be ok..the harness of the vans dist. Wont work on the camaro.. The harness is diff.buy a dist for the 76 camaro with a 305(there cheap)...
