Spark plug recommendations ????? Champion 113 at .045 is what I have so far after looking at all threads etc. But I am sure I am overlooking other possibilities.

Autolite Platinum Spark Plug
Part # AP145

Advance Auto has these after rebate(s) for $1.69 each. Anyone use these???

Re: I looked at other Treads but---------------
 

Dude, Champion? Autolite? Are you a Ford guy trolling the Chevy forums?

Re: I looked at other Treads but---------------
 

That's what I was thinking haha

Acdelco works fine

LMFAO You young guys are a riot. Its a spark plug not a life and death decision based on brand. Just looking for what works. To funny. At 71 have more to worry about than brand names. FYI bought Autolite AP145 Platinum for $1.60 each after all Rebates delivered to my house.

In that set up the name brands will not much matter.

We use Autolites in a 700HP dirt late model engine and it is a SBC to boot.

To some I guess there is a line in the sand. LOL

Autolite 26....why? I like autolite because they work fine and its a simple number to remember, and ask for.
