what plug be best ?

[richardv6]

I am ready to install spark plugs in my new ta build motor and like sujestions on what best to use,i am using stage 2 heads on a oncenter 273cu .I plan on running pump gas and running 100%methanol.

Something with a non-projected tip.

 

[richardv6]

got any part numbers of non projected ones.

 

[BEATAV8]

Sure. But I am accustomed to running champion GN1 heads which use a 14mm thread, tapered seat, 0.7" reach. What is the thread on your heads?

Try doing a search. I do find it disconcerting that you have this high po big build and arent even sure what sparkplugs to run in it?

 

[richardv6]

I was just asking opinions ,I did a serrch and have a idea of what I want to run just want to see what others are running with alky...no need to be a smart ass.

 

[richardv6]

this is first time I am running stage heads also.turbo nasty.

 

[richardv6]

I believe tapered plug and .708 reach

 

[turbobitt]

I run AR-472 thru AR-474 on my Stage heads. These are a tapered seat plug and .708 reach.
