I have a Red Diamond 406 in storage. Factory idle is (IIRC) 475 rpm. Should just about be able to count the cylinders. : ) Seems I heard somewhere someone had a Mercedes aero-engine that would idle at 275 rpm. This does not include various massive industrial engines like the Fairbanks-Morse that I've seen pictures of whose MAXimum rpm is 120. With a 48 inch stroke, you don't want to push it. : ) Ken Quoting das24rules@xxxxxxxxx: > -It's a funny exhaust note > though, that oddball cam with a turbo muffler, 2.25" pipe that exits in > front of the rear wheel.- > > casper is done the exact same way. 2.25 exhaust. i run a "thrush" muffler. > sounds pretty cool. a year ago last july, i was at the big boise car show. > "north west motorfest" and they shut down the streets in down town boise, > idaho. i was there cruisin, idling majority of the time ya know. and i had a > couple of people thought that i had a serious cam in that thing. i had the > valves adjusted just a weeee bit tighter than they needed to be, and for > some > reason it was wanting to idle at about 450 rpms that night, so it had a > serious loping sound to it. like an aggresive street/strip cam. ran GREAT > that way, but it was only that night it sounded like that. anyway, had a > couple people thought that i had hotrodded it ALOT, and 2 guys that knew a > little about that 196 asked me how i got it to run like that. i just told > them that the valves were a little tighter than spec and the exhaust, and > thats how they are. i think they sound just friggin AWSOME myself like that. > that long stroke, little lope, and a great sounding exhuast note. there is a > video footube where you can hear casper's sewing machine going by. if you > look up "northwest motorfest" and get the video of the 2008 country cruise i > think is what its under. its a ways into it, but you see/hear casper go by. > sounds so funny, because you hear these v8 hotrodded cars go by with that > nasty loud v8 rumble, then you hear this little sewing machine go by.
