Re: Restoring Rusty
Spark plug gap on a HEI Chevy should be .045 as .030 was for a points system. Yes using the wrong gap will make a vehicle run like absolute crap. When I put plugs in my truck they were gapped for .030 and I could not get it to run properly no matter what.
Also doing vac gauge measurements I am pretty sure it should be on manifold vacuum not ported vacuum as should your distributors vacuum advance to get optimal performance. |
