Thanks for the welcome everyone.
Boger help me out with some definitions:
what is FWI, U-bend, downpipe and PCM. Sorry to sound like such a novice but the last several years as a banker have not exactly equiped me to twist wrenches right out of the gate! Last time I got grease under my nails, tweaking your engine meant adding duel exhaust or swapping out a two barrel carb for a quad!
Thanks for your help!
