" From: Tom Jennings <tomj@xxxxxxx> " " This Navarro block, the bore is undersize. I measured it three " times. " " 3.595" diameter, all concentric, no ridge or damage. Weird. Makes " for some damn thick cylinder walls though!! i bet they were aiming at 3L disp for some reason. indy class regs? quick calc - 3.595" x 3" = 182.71 cubes. " So none of the pistons I have are from this motor -- they're all " 3.75" (well, they measure 3.735"). " " Can forged pistons be reground? They have practically zero hours " on them. I've got nine stock diameter Venolia forged 199 pistons. i'd be tempted to keep these original and have new venolias [or ross or whatever] made, to the small bore. " Found all the wrist pins plus a dozen extras (floating type) and " 2X solid lifters and adjustable pushrods. saw your cam notes on the pg. there -was- a [paul?] winfield in the early hotrod days. maybe he was a big-time indy mech in the late '60s. if you do have a roller cam -- you'd have a fun time getting them in there, but with custom tiebars you -could- run mopar rollers. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
