Can anyone recommend a spark plug for a low deck with Trick Flow 270s? Thanks Birdtracker NGK-5671-A-9 in my 240's, but the last number is dependent on usage and fuel type.

Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.

I'm going to assume that those heads use the 5/8 body .750 long spark plugs, if that is so I would start with a set of Autolite 3933 and see what they look like. My E85 motor has a little more compression than yours does and DOES NOT like the next step colder # 3932 plugs   I've been told by several different E85 racers that E 85 does not need or like colder plugs IHTHs

I wouldn't waste my time or money on a "trick" spark plug, my old airplane motor used what is referred to as "massive gap" spark plugs, it has two grounds that are set at .015 gap on each side, it runs two plugs per cylinders and dual magmeto with each mag firing one spark plug per cylinder. Max RPM is 2700 Years ago their was another multiple ground electrode spark plug company around, I can't think of the name of it now due to it went B.K. from lack of sales, the proof is in the pudding

12.3-1 is the compression ratio. E-85 or possibly 110 race gas for fuel. Thanks for the info. Birdtracker # 8 NGK..............
