that is the motor I was thinking of more or less exactly. Who built it up, what do you have in it, what induction, valves and is it hydraulic or slid lifters. Lastly woudl you say its a smooth refined type motor once spining.
It was originally built in the US but quickly developed some issues for various reasons that I won't bore you with but include some of the worst "mechanics" (local) I have come across in my life and one fraudster (also local, and yes police are on his case but they are taking their sweet time...)
Now has new liners, Auscrank race crank, Oliver rods, not sure what pistons ATM but forged, solid roller, ported AFR 185s. 52 mm 8 stack, Motec and dry sump.
Was rebuilt by a friend in Australia.
The V8 supercar and I were well clear of the rest of the field which included Porsche Carrera GT, Murcielago, Gallardo, 458, and various other supercars and race cars.
In other words the engine is strong and revs easily to the current redline of 7500. With current internals I probably should be revving higher but didn't feel the need.
Refined? Hmmm, depends on your definition. Personally I wouldn't say so but it isn't horrible. I can happily drive it from one end of the state to the other, although earplugs are your friend... It runs very sweetly under normal road conditions.
Apart from induction and exhaust noise, there is also valvetrain and ancillary noise. It is fairly smooth under normal conditions considering the cam and really wakes up if you open the taps.
I have a Merc' ML500, that has what I would call a reasonably refined engine. Others would still argue otherwise and say their Bentley is far superior.
Compared to what I originally got from the US and the awful tune it got when it arrived here - yes it is refined.
