Re: billet even fire
Odd Fire - well that's a tough one as now one know's for certain. Mike Lee is over 1000 hp and so is John Fry. However both have are very good a tuning and figuring out how to wire them to run on Motec and on Tek III. Guy R also just completed a Odd-Fire motor and has worked out the bugs with the Fast Set Up.
Your other option would be to run bank to bank odd-fire similar to how the Hoovers are running there set up.
PS - Odd Fire will also shake you to death on the street similar to a Harley and make sure you have plenty of lock tight as things will and do come loose.
My suggestion - build a v8 it was save you a shit load of money and is much more reliable. And who cares what people think if it's not a v6.
