In normal everyday use we keep it set at 1800 high idle, pulling down to 540 pto rpm, 1600 engine, I've seen 65.    I would dearly love to know what rods were used. Freind is now deceased. I suspect it is really just a Super 99 gasoline engine with rpms "way up", but I don't know how crank would have been cut. I was told that every part in that block was available in March of 1977 from WHITE.  If it makes any help, mains bearings  are 2.5", rod bearings are 2", so crank may have been ground off-center enough to get stroke.  It's been a while since I played around inside a Super or Fleetline and if memory is anywhere near correct a Super should have 2.5" rods and mains, with a Fleetline having 2" rods.

Actually it is a 57 paint scheme. Serial number is "amoung the missing" so we aren't really sure what year it might be. Dad bought it new in fall of '55.   Original block, 3.5x3.75, punched to 4.0, stroked to 4.0, should make a 302 same as Super 99 gas,  1100 MF, gas, or 1850 gas.  Real trick was a 4 main bearing crank. [/quote:3uizzpcy]
O. K. So it is a 302 not a 320 like a massy or 310 like the 1850. I was interested in stroke. Ask your friend what rods he used. Does it have a grddle in it? Any ideal what for horse power you have at 1750 0r 1900 Around here it is 10% over stock.[/quote:3uizzpcy]
