Darby, yes it's a stroker=467 cid. The carb we ran was actually not mine- Ran a quickfuel, 650 i think. I had a vaccuum secondary carb that they thought wouldn't work correctly on the dyno. (thought probalby wouldn't open the secondary's correctly). Cam is solid roller, custom grind- 236/242 @ .050", net lift with 1.65 rockers is in .610-.630 range, 110 LSA, installed at 106 (or is supposed to be anyway.) I was really surprised at the torque figures it produced. it actualy touched 580.x in one run, but the printout was the best hp number.

Bill, ya looks like it dropped some... I'll cut into the filter before I get it in the car. This was an all new motor, broke in a tested in the same session.

Actually blew a head gasket the day before, but didn't do any damage to the rest of the engine.
