Thank you the tunnel wedge question worked. I personally am not into who has more horse power than who... I think that 740 HP is excessive for a street car to begin with. But that being said the motor you have is very nice.

I already have a nice set of Shelby heads that will make every bit of 650 HP and 650 torque, however my builder prefers the Blue thunder over the BBM. The BBM is a very nice product and would be my second choice.

Perhaps it is, but my engine has a special feature. If I only push the gas pedal half way down, it automatically drops it's output down to only 370 HP or so - perfect for those days where I might be thinking that 740 HP is excessive. Then, on days where I want it all, I just press the gas pedal down further, and presto, I have 744 HP.

Who is paying who for what?

The builder should advise for sure, but wanting you to buy parts that you already have seems wrong to me.

When the builder thinks he is in charge of spending my money, I think I would look else where.

I would feel different if you had junk heads, but you don't. If he cannot make good power from those heads he isn't worth is weight in ..... never mind. I said my piece.

FYI my "builder is a close friend" I am gathering parts for a future build. When you see what Im building you will understand...

I was afraid of that, which is why I stopped.

I hope he does well by you and you are happy with the results.

Good Luck
