Cool, text me once you talk to him. Hopefully he will have it done so I can pick it up when the block is finished.

Hopefully he sticks to it this time.

I'm not holding my breath

Call him tomorrow and tell him I'm picking the block up on Friday and that I will be by to pick up the cam. Maybe a little pressure will help.

I've been putting pressure on him, every day, stressing how much I need the cam so I can assemble the engine. It's how he's always been.

I picked up my block and cam today (thanks again for picking the cam up Guy!). The new Probe pistons measured 4.026 so the block was finished honed to 4.031 for .005 clearance. Cam specs for my American Custom Cams cam are .555 lift with my 1.7 rockers, 218 at .050 with a 114 LSA. Tomorrow I'm going to start building.

Glad to pay back a favor

I didn't get much done today because I ended helping my neighbor install the trans in his Chevy 1500 P/U.

I started on the pistons after though but only got 4 done. I'm smoothing out all the sharp edges. Believe it or not, it took about an hour per piston.
Before.

After.

I worked more on Sunday. I started by washing the block. Then I chamfered the oil holes on the new crank and washed it. After that I measured all the journals. I then moved back to the block and installed the main bearings and then the crank. Main bearing clearance is .0025. I'm also using a Milodon windage tray so I had to tap the threads for 2 and 4 main caps and then installed the studs for the kit.

After I finished installing the crank I started assembling the pistons and rods. I know I mentioned this back when I help Eric build his 331 but I hate polylocks! So I got all the rods and pistons assembled and then start file fitting the rings. The CHP kit came with prefit Mahle rings (Perfect Circle) and I must say I'm glad that I don't just slap them on and install the pistons. They ranged from .008 up to .016 gap. There instruction sheet recommends .024 - .026 for both the top and second compression rings. So I set the top rings at .026 and the second at .024.

I didn't have much time tonight but I did finish file fitting the last four rings and then installed them onto the pistons. I also measured the side clearance which was .002.

Here are the only pictures I took.
