Dynoed my 360 with 671
Finally got my blown 360 on the dyno. This is a basically stock bottom end. Cast pistons, cast crank, stock rods, balanced. It had speed pro pistons with little use so I ball honed the cylinders. Ground the crank and found some resized rods. Moly rings, 7.8 to 1 compression. Old Wolverine 238 248 @.050 114 lsa solid flat tappet. 273 rockers, 1.88 1.60 valves with some porting and good valve job. Howard's valve springs, stock retainers.
Old used 671 10% under driven, the carbs I had and are dual 600s jetted from Edelbrocks hand book. It made just under 8psi at 6k rpm. Which is where I cut it off, being stock internals. Idles smooth and runs very nice.
