To run a huge throttle body one must enlarge the intake tract . So the welder and lathe were working overtime this week. Compare the 42mm to the 46mm and then the 50mm .
I have not decided what size engine this is going on. The throttle body height is also an inch taller than the stocker so there might be a redesign like bolting the TB directly to the head instead of the rubber boot setup. I am curiuos if vibration would affect the sensors or IAC.
Make it a 460. That way I'll know if I want to do it.
This head is also getting the prototype exhaust valves. So I will have to use the 98mm pistons for clearance. Ive shaved the head more for more compression as well so I have to clay it for clearance. I just sent my last CP piston to Tim so it will be a Witech piston instead.
