I'd have to say just one thing... MPI!!!! I'm plannin on that cam later
this sumemr, although I've got to deal with my exhaust and gettin cold air
to the motor first. As for the plugs, I'd suggest a colder range Autolite
I'm runnin 3923's (2 range cold) which would convert to a 5223 plug (the
power tip thingy I still don't understand, gonna have to compare those).

Dynoday is May 20th, I'll have several diff plugs there to try out after I
get the MPI comparison runs done (only mod I've done, get some hard data)
Since I'm startin a job at Carquest this week, I should have no prob gettin
a bunch of diff plugs to try out.
