ACDelco R45TS Professional Conventional Spark Plug (Pack of 1)

Q: hi i have a 82 monte carlo converted to ss whit an carb 350 that uses r45ts is their a double platinum version of this plug?

AC Delco 41-905 is the platinum spark plugs.

Q: Where is the spark plug made in uysa?

The package says Made in Mexico.

Q: Does this fit a 1974 corvette 350 SBC?

I put them in a 79 vette 350 So I would think they would work.

Q: My 1974 corvette 350 has been converted to HEI, what should the correct gap be set to for best performance?

Ask the HEI manufacturer. The gap is determined by the engine compression and voltage of the spark. If you can’t get an answer, start at .045 and regap after trial runs in .005 up. If it gets worse, reverse sets until you find the best results. Sorry no easy proof.
