I've just finished putting together the sort block on my latest engine combination for my 750kg circuit racing oval.
Here are the specs:
Counter-weighted crank,
Balanced rods & pistons,
Aircooled.net / DRD level 5 heads 40 x 35 valves, mini-D ports and 45cc chambers (9.6:1 CR) with match-ported tall manifolds,
Engle W130 cam,
Reground lifters,
30mm shadek oil pump and full flow system,
44 IDFs,
Standard pushrods shortened,
Standard rocker arms,
Berg 1 5/8 header &
2 inch flange & muffler.
Okay so this is a relatively boring engine combo compared to some of the mega-size mega-buck combos on the various forums. It's designed to be tough so I can drive it 300 kilometers race it in sessions up to 10 minutes long and then drive it home again.
No trailers here.
