So I'm running a 318 with kb167 pistons. and with stock rods my deck height varrys from .0035 above the deck to .008 below the deck (.0115 variance) depending on the cylinder. I have already rearranged the piston/rod combos to the most ideal cylinder, longest rod to the tallest deck cyl. and shortest rod to shortest deck. I measured with a dial indicator on a magnetic base arm and zero'd it to the deck, measured each from multiple mount points and each cylinder measured within a range of .0025" or so (ie. the tallest piston is #4 measurements varried from .00125 to .0035 above the deck by pushing up/down on the piston and different mount points, and the shortest was #3 from .0055 to .008 below the deck).
Should I be worried about this differance of rod lengths?
Anyway I'm getting close to finishing this engine up ( just need heads and cam). more info on my build at a previous thread: http://www.forabodiesonly.com/mopar/showthread.php?t=212457
just throwing out my used cam and going with the smallest of the solid/flat voodoo cams(60440) or xtreme energy cams(20-230-4), both seem similar.
I am looking at the felpro 1008 gasket with the edelbrock rpm heads which would bring my piston to head clearance between .0355 and .047 depending on which cylinder assuming i get exactly .039 compressed thickness from the gasket. Which from what ive seen in my research is pretty wide range for a quench benefit, meaning little-no benifit on the shorter rod'd cylinders. I've already had the rotating assemply balanced so i dont want to switch out the rods now... But I would appreciate advice.
