Marshall's current M10 is a nice, smooth powerful engine. The valvetrain is very quiet (even with a Schrick 292 cam). I would buy it if I needed another non-tii engine and had the room to store it.
This is the motor I built way back in '01-'02 for the malaga 73 that it came in. Whoever got it - let me know, as I have all receipts for parts (new .050 over Mahle 9.5:1 pistons, Schrick 292, Schrick HD valve springs), machine work (John Spindler) and head work (Eric Kerman). Also had tons of receipts for the other stuff - suspension, brakes, etc. I never got these to Rob, who bought the car from me in the summer of 2007 before selling to Marshall.
Would love to hook up with whoever got the motor, as I put a lot of money and love into it (before eventually neglecting the car for the last coupe years as flyfishing took over the addictive part of my feeble brain).
