blow 468 running autolite 144 plugs, they give a good read

Mark, I don't know yet if we'll be there. I'll let you know.
I'm not going to run the engines at that power output. I'll drop the boost down to 3 lbs, whish should give my around 575 h.p. But it sure sounds nice at 7 lbs. It idles at 800 no-load on the dyno, and at 575 h.p. I should be able to run 65 mph.

NGK all the way. BR6FS

Any problem with running A/C Rapid Fire #10's in a stock 454/330?

NGK UR-5 - 383 N/A stroker small-blocks.

Having a hard time finding the UR-5 plugs lately. Discount Auto (Florida) alwas had a load of them in stock, but since Advance bought out Discount Auto, they lightend up their NGK line.
