Huh??? Wha...??? Please do your homework! Get EVERYTHING IN WRITING! Do only what you know will work for you! BE SURE TO KNOW WHAT WILL WORK FOR YOU! I need no more work (and I am not spamming here), but you should know how all of your motor parts/ machine work is working for you. MONSTER parts alone, do not make a "bitchen'" motor. Over the past 27 years I have tried to be within a 10% total of my estimate. If your motor builder knows his 'art', he will give you an accurate estimate UP FRONT! Many HUNGRY people 'SHOOT LOW', and end up way off of the price charts. You bring me the parts, and within 3 days I can tell you where we are at! I still don't understand all of the MEGABUX motors that are being sold. You are on the internet, you can look up the retail prices of parts. I guess it all comes down to how much YOU are willing to spend on "name brand dyno time"? Or was it the magazine BS that got you to buy?
