Teratonga your right there the only other mod I would do to this engine would be fuel inject it cost around $3000 for the setup quad 45mm throtle bodies injectors. computer ect for around
10-15 extra hp I dont think thats worth it. To build an engine to same spec would cost at least $6k Aus.
Davo if you really want motor you had better save harder :) hehe. I dont have all the spec it was done in several different stages with different cams tried ect ect,. The main thing is
the Angine hammers all day everyday.
Terratonga A trip to mudgee from sydney would be around 3hrs west.I hope your strong to carry that engine and box LOL
