what gap do you guys set your plugs at? not really sure what year my engine is out of and not sure what gap to set my plugs at? thanks

Small block to big block, carb to TBI all makes a difference, and it is best for one to know all the correct info, or your truck will run like crap....

Type of ignition would help also.

Can you just pull a plug and call Autozone with the plug number?

what gap do you guys set your plugs at?

Since you are asking what gap "I" set mine at, versus what should "you" set your gap at, I set mine at .035 for my 5.7 engines

sorry guys i wasnt thinking and i didnt give you crap to go off of. ok its a 73-75?? frame with a small block 350 .030 over. stock heads performer intake and a 600cfm edelbrock carb. i am pretty sure it came with points but some one at some point switched it over to electronic ignition. i looked in my repair manual and i have alot of different choices from year to year for gap setting. i put plugs in it but am second guessing if i have the right ones in. i bought plugs for an 81 cause thats what the cab is. also it runs like crap untill it gets warm. thats kind of why i just got to thinking about it. thanks

What # plug did you put in? R44T?

You should get plugs that are right for the engine, not the truck cab. A truck might have a different engine than original equipment, so the plug to use may be entirely different. I use a plug in my 87 tbi that's an R43T gapped at .035" .My engine is not built up for performance. You can safely go up a heat range- to R44T, as Vile says, but be cautious not to go so high in heat range that you damage your pistons and blow a hole in the tops of em..
 You can do a search for engine identification and find some info on where to look for your engine's id.
