I had some problems with my first rebuild. I put an old timing chain I had laying around and that caused some problems. I also didn't get the crank polished or anything and I ended up scraping the main bearings. All this just on the dyno haha! Anyway I got the crank from the machine shop, getting new Clevite 77 main bearings and Stangfreak's old timing chain/gears so I can put this engine back together. Next time I take anything apart again hopefully it will only be the heads as I plan on some nice heads to complete the setup. I'd like to dyno again but my friend doesn't have time for me unless I pay full price so... blah!
