Just curious not being cheap.


Can a set of AC Delco Platinum 41-921 spark plugs be used in a 94 351 motor?
I currently have about 6 sets in perfect condition and no Chevy car to put them in.
I checked the internet for cross reference charts and came up with nothing.
Not exactly sure if they are the same heat range also.


figured I'd ask here.


I'm going to be doing a tune up right after plow season so if the answer is a NO, Ill be buying plugs. Any recommendations on plugs and wires? Accel?

 

I can't say for the AC Delco plugs, but for these vintage engines, regular Copper core plugs are the best! Either Autolite, Motorcraft, or NGK plugs, from the cheapest to the expensive.

As far as plug wires, Either Ford Racing or Taylor wires. I've used both. Taylor is high $$ and Ford Racing wires can be had for $45. Both good sets.

 

Here is a cross reference for that AC plug...

Gonna stick with whats supposed to be in there and sell the Delco's on ebay or something.
