Just trying to finalise the spec of my new engine, and I'm tempted to buy a set of steel rods, but am I wasting my money?
spec so far:
Omega pistons with deeper pockets
QED 450 Cam
Waisted stem valves (maybee +1mm on inlet)
3 Angle seats
It runs on 45's at the mo, with 3D ignition, do about 4000 miles a year with some sprints and track days thrown in.
I'm aiming for a reliable 220 brake, with a rev limit at around 8k, question is do I need to do the rods?
Do rods age (creep) or is an old rod assuming it's geometrically the same as a new rod as good or ...better (like the ex road car blocks BMW used to use for there 1000+bhp F1 engines)
