Some street work and some club level circuit racing - ie Winton, Phillip Island. Aiming for 430 to 450 hp and 440 to 460 ftlb. Desired shift point shall be between between 6000 & 6500 rpm.
I still desire some streetability and fuel economy - ie 25 l/100km. I believe this combination should have a similar low rev torque curve to the engine that the heads were pulled from. Details of this motor are shown in italics in following text.
Have considered a stroker for extra drivability but the extra expense of around $2000 would yield better results if spent on a roll cage or race seats.
There is a similar engine build on: http://www.fomoco.com.au/Funnelweb.htm
