BBB Big Bore Boss 322
Now that the BBB (big bore boss) is built, installed, and tuned the next thing on my list is to assemble the old block into an engine. I have plenty of spare parts around the garage.
Today I cleaned up the decks. They cleaned up fairly nice. Notice the 25,000 mile ridge, I don't think it's too bad at all. I've already measured the end play and side rod clearances. All is good. So good that I'm not freshening up the bearings. It used no oil and the phasers always worked as commanded so oil flow was good to the top end.
Tomorrow the deck surface will be verified as flat. The two almost new 2009 heads that are going on it will be cleaned and straight edged. Then they are being bolted on and I'll have a nice long block on the stand. Compression will be 11:1 with the flat top Mahle pistons and stock combustion chambers. It's a little over 285 cubic inches because of the .030" overbore.
I had originally planned on building a whole motor but for now it's just going to be a long block. I'll probably put the windage tray and oil pan on too. I have two oil pans and two new gaskets, lol.
