Re: Build Thread...1979 GMC 1 Ton Camper Special
For my GMPP 350/290 hp crate engine (same vintage engine as your truck), they recommend R45TS plugs, gapped to .045 For HEI Distributor.
For the stock Goodwrench 350 crate engine they recommend R44TS plugs, gapped to .045 For HEI Distributor. It sounds like .045 would be right for your engine. Bruce |
