I'm looking at getting some forged pistons (+0.050) for a 45" sport scout. I want tough stuff for the extra 12" cube stroke. I need some advice in regards to ordering them. I'm cutting down a set of chief 74 wheels (Yes, all Ingin, why not). Havn't done this yet. Stroked 57" w/ stock rods, stock 640 cams. Barrels are square bottom reinforced cast.
Stock Bore: 2.875, Stroke 3.5, Piston clearance 0.003".
What should the deck height be? Rod center to deck height piston. I think I'm doing this backwards. I should be measuring the clearance from an assembled state. I want to avoid shimming up the barrels. advice?
Specs: Flat top, 3 ring plus oil control ring, no t-slot(forged), spiral locks, wrist pin oilers cut,
Cam-ground (.006-.010): Bottom -.005, top-.007, ring lands .020, ring joint gap .015-18
Pin fit Piston: push fit, Pin fit rod(honed): 0.0015,
Any technical advice appreciated.
