As Jake said. My PMC is pretty much the last example he gave.
N42 oversize to 89mm bore.
Ported P90
FJ20 forged spool rods.
Custom forged domed JE pistons.
75 deg high lift cam.
Prepped crank.
ATI harmonic balancer.
Recurved dizzy
Lightened flywheel.
Triple 44PHH Mikuni's.
Custom headers, designed by the late Peter Hall.
And more.
This will spin to 7,500rpm all day, but I don't do it.
It's made 146kW at the wheels. But that's only at 6,000rpm as the exhaust needs to go up to 3" and change the cam to a 76deg. Then it'll go 160-170kW's.
What you're proposing Zac, will be a fun cheap motor.
What Jake and I have are not cheap, but very good. (Jakes is a bit mental)
Pick 2 of these. Good. Fast. Cheap.
Good and cheap. Not fast.
Fast and cheap. Not good.
Good and fast. Not cheap!
