Spark Plug recommendation; blown 360

Kern,
Thanks a lot for the info and photos. That's a real sanitary installation. Can you tell me a little about how it runs, and your cam specs?

I have no idea as to how this engine of mine is going to react to this blower. It's a Vortech "V-1." S-trim. I have pulleys sized to gine 50-K impeller rpm (design-spec maximum recommended speed) at 6,00 crankshaft rpm, my redline.

The engine is a VERY mildly modified 360 Magnum with pocket-ported (only) heads, a 3-angle valve job, 9:1 (true) compression, and a 214/218 degree at .050"-lift hydraulic roller cam, (114 degree lobe separation) using a 750 D.P. Holley carb modified by the Carb Shop for blow-thru. It has a 904 tranny with a shift kit and a 2,500-rpm-stall converter hooked to a 3.55 Auburn Limited Slip 8.75" rear.

I am looking for plug recommendations, as I don't have a clue (beyond the good advice from Bob) as to what might work well.

On a 95-degree day, my car ran low 13's normally-aspirated, with 340 exhaust manifolds and an M-P water-heated intake manifold with a 750 Holley on top.

Now, it has TTI step-headers, a "Chinese Air-Gap" and an 850 double pumper, along with the blower.

The car weighs 3,340 without me in it... 60-foots are 1.91 usually, on 8"-wide drag radials.

I am trying to pick up a second on e.t., (low 12's) and I realize that's a lot....
Can I do this??? Did your car pick up a second with the blower?

How much boost do you think I might get (and, how much do you run???)

Thanks for any ideas, information, or suggestions!!!
