[RICK LAKE]

hoodR1 Rick it's more important That the bell housing be centered on the block. DON'T take their word for this. IF this is not done you are looking at possible major damage to motor and trans. I pilot bearing can't offset this problem.
2 small notes, have sure you measure the input shaft length the then the distance from outter bellhousing surface to bottom of crank and pilot bearing. IF you don't and the trans input is pushing against the polit bearing you will wearout the thrust bearing one one side that centers the crank in the block.
Last note, take your time and check everything twice. Both Lakewood, ( major adjusting) and Quicktime( smaller adjustments) need to be centered.
Good luck with build. Make sure the starter has enough engagement on flywheel or this will be the next problem you will face. See thread with Large Arbor with starter problems and prewearing out the bendix drive teeth. Good luck Rick L.
