So, after plunking down $298 for a block of 6016, it was back home to find an MP62 housing waiting for me. <img src="/forums/images/graemlins/kewl.gif" alt="" /> I disassembled the MP45, swapped the bearing plate and nose drive onto the MP62 housing and started final fit on blower location and plenum sizing. I reduced the height of the plenum to 1.00":

Located the blower:

Checked to see if I was in the ballpark for this belt (fingers crossed):

Calculated the volume in the MP62 discharge port - it's 25.0 cid:

Added the volume in the discharge port to the volume in the plenum and glued in some sticks to adjust the final volume to proper size as suggested by Helmholtz Resonator Theory - total plenum/discharge port volume is now 91.5 cid - exactly 1/2 of 183 cid engine displacement:

The idler pulleys should arrive soon, so the next session should see an idler pulley bracket/nose drive brace mock-up... if the belt and pulleys will work together as planned.
