I made a few random posts, but I figured I would make a thread regards my motor rebuild for others to reference to easier. I did a quick search for rebuild threads and found none
Our rig currently has just over 203k miles on it, so a fresher motor will give it back more pep than when it was new.
I got a used (140k mile) motor from Ebay for $500 over a year ago. It sat on the motor stand until I got sick of looking at it and having to move it to get to other tools etc
Got the motor stripped down to a bare block on Wednesday and I thought all looked good
Here is the block all cleaned up:
Yesterday I got the heads, pistons/rods, front cover/oil pump and all other bits and pieces all cleaned up as good as the block. Then I ran down to my local expert machine shop (PMI in Jefferson City) for them to accurately measure everything and check for any run out in the bores etc. I measured the bores, pistons and bearings myself and all looked good to me.
PMI called today and gave me some not so good news...
The bores are 3.5 thousandths over stock size.
The pistons are 2 thousandths under stock size.
Main bearings on the crank and block are "just' within specs.
All this will result in a 10/10 grind for the crank and a 20 thousandths overbore.
The rocker shafts will also be new, along with the supports that D&D manufacture (seen on the lower part of this page http://www.aluminumv8.com/new/newstuff.htm)
I also plan on an oil pump rebuild, new freeze plugs, full gasket and seal set, Crowler cam, lifters and cam bearings, timing, timing chain set and ARP head studs.
I will also be balancing the rods/pistons and stripping the heads down to relap all the valves by hand and put new seal on them. Maybe clean up any casting marks on the ports and call it good.
Any other suggestions while its all apart?
Will post updates as and when they happen. Got to order some parts from D&D to allow the machine shop to do their thing, then start the reassembly when time/funds allow.
