Plug recommendation.... Not LS based but need to know which plug for a 250 shot. Set up is SBC 377 w/ 13.6:1 . Current plug is an autolite AR3933. Thanks in advance. Sean.

Not sure about an Autolite, but in an NGK, if it were mine, I'd be looking at a -10 heat range plug in the correct thread and reach for your heads. This should be about right for your compression and shot size.

Yeah but what is the part #.
For example a b8efs in NGK is a 8 heat range plug for an LS motor with a tapered seat.
a r5671A-8 (I think thats the part number) is also an 8 heat range plug but it is a gasket seat plug but it is still an 8.
