I just got motor back from the machine shop and am finishing it before dropping it into the engine bay. I was curious if someone could suggest spark plugs to use for my combo...

331 Stroker (8.5:1 Compression Ratio)
FMS Cobra Upper and Lower
FMS X-303 Cam
Trick Flow Twisted Wedge Heads
Vortech S-Trim Blower
MSD Boost Controller

Thanks ahead of time...

Denso Iridium seems to be the plug for blowers. Hope it helps.

I think he was looking for something more specific, like what plug would be in the right heat range for it, not a brand, but if you want the denso iridiums which I also hear are good, get the ITF22 I think is the part #, I am pretty sure that is the one a range colder than stock
