Did I buy the wrong plugs, again
When I put the motor in the car, I had the points set-up and I put in the ACDelco R45S plugs. I found out that those plugs were for the 1968 455 motor, and not the 350 like I thought in the first place.
Today I just installed a new set of R43S plugs, The plugs that are for the 1968 Olds 350 motor. Car runs great, doesn't have that little shake at idle that it did with the R45S plugs, but now I'm running a 1978 HEI distubtor from a Cutlass, should I have bought the plugs for that distubtor ( CR44TS, CR45TS, R44TS, or R45TS ) or will the R43S plugs be fine? I did gap every plug to .045

Is your distributor from a vin "R" or vin "L" 78' 350 motor?
vin "R'' motors are .060 and vin "L" were .045

I have no idea.
I only found out it was a 78 dis because I replaced the advance. It did run good, but made that cyl sturggling noise when pushed I bought it at a swap meet

Well amigo, The best thing that I can think of would be to get a few sets of plugs and try different gaps.
the best thing to do would be to get it on a shop dyno and get your timing curve adjusted for the most hp that you can squeak out of that thing. It's probably 50 bucks an hour, but you may gain 30 horse out of it.

You've been misled, by the "experts" because the concept seems to be too simple for them to grasp. Norm
