i know this is going to be basically a personnal choice but what is the best brand of plug to put in a 75- 350? right now PO had autolites put in. i myself have never had luck with champions although that was years ago. is there a brand that is used that generally has good performance? thanks for any input

I'm assuming the engine is still stock.
 I would try out the AC Delco Rapid Fire plugs P/N- AC 10.
That would be a direct replacement for the AC Delco R44TX spark plug.
I've had good luck with these plugs.
And that's my .02 cents. 




GEN III 5.7L "LS6" Engine swap
TKO500 5 spd.
3.54 Dana 44
'69 "N11" Sidepipes
Borgeson Steering Box

I'm partial to AC plugs, myself. Been working just fine in all my GM products for many years.
Autolite plugs are good for certain high rpm situations, but not as good as AC stuff for every day driving. My .02

 Sorry guys I run Champions in everything. Never had any problems at all. I had a 400 small block I'm my 71 Camaro it turned 7500 RPM on the street never skipped a beat. In my motorcycle turns 10,500 Red line on Champion Plugs. All tho in the spring I plan to try E3 Spark Plugs in the Vette and see how they work, if they don't work out I'll go back to Champions
