I have a 1966 steel crank 318 I picked up because I needed the 360 heads it was wearing. Guy I got it from told me he thought it was “built pretty good.” He pulled it for a bigger motor in his B body. I have torn down my fair share of motors that we’re “running when pulled” and most must have been powering submarines because they looked like shit when you started to tear them down. I’ll be sending everything off to the machine shop for tolerance checks and a good once over. Cylinders are clean at .030 with a flat top down in the hole a bit so I am considering upping the compression to at least 9.5:1. I have set of fully machined 360 heads with bigger valves ready to go. The rotating assembly had meat taken out of the underside of the pistons, crank, rods for balancing. All bearing surfaces looked great, mains were standard, rods were standard or .0001. Not sure I can get the latter anymore so those may have to be turned. Intake I have on hand is Performer RPM 318/360. I am going this week to pick up and LD4B and can also get ahold of a Performer Air Gap. Whattya think?
