OK, it'll be from memory because my engine file is at home.
It was built up by SBD [but don't talk to Arnie for too long aobut them...] incorporating Omega pistons, modified con rods, balanced crank, lightened flywheel, alloy front pulley, Group A valves, modified head, SBD high lift cams of course, Pace scavenge pump, small Suzuki alternator, Lumination TBs, MBE ECU, open timing belt and a few other bits and bobs that I can't remember. I've got a Dyno plot too, which shows 246bhp at around 7250 or so and 181 lbs/ft/ at 6750. In real road driving it pulls like a train from around 2k, with real power coming around 3500, and BIG power between 5000 - 7750. It's also reasonable economical, driven sensibly, I suppose between 25-30mpg, but this can easily be reduced to the high teens with spirited accerleration etc. Still far better than a X/F though.
is this the sort of power unit you had in mind?
