original numbered 340 engine in car, working on spare '70 340... wanted to use that as the 'toy' engine due to higher comp ratio, forged crank, internal balancing... crank ground 20 under on mains, 30 under on rods before I got it, but it polished up really nice using 400 wet-or-dry and leather shoe-lace... ; ) (one of the old-timer's tricks...) got all the journals within .0002 of each other, so all have to do is plasti-gauge them. Bores were mic'd at 4.0415), and only 2 thou taper, 3 thou out-of-round, so hone should fix up nicely. Can't believe it wasn't bored over by now...
Anyone... any idea how much you can fly-cut stock flat-top pistons??? the spare came with a mopar purple-shaft with .484 lift at valves (vs stock .422) on both intake and exhaust... one of the previous owners of the spare engine tried runnin it without relievin pistons, and I got some contact marks on tops of 4 pistons, and some bent pushrods. I'll fly-cut reliefs about .040 to .060 if enough meat to work with... they also ran the thing with rocker arm shafts upside down... OOPS
[made a good deal for me, though! 8 ) ]
