Retapping the block brings back nightmares. Be sure your tap is correct. I retapped the headbolt holes ona 350 4bolt main years ago with a Snapon tap that was marked correctly for the bolt holes, but when I tried to bolt the heads on, a couple stripped out on me. After alot of head scratching, agrivation, and heli-coils, I found out my bottom hole tap was labeled wrong. The pitch was different, but it wasnt that hard to tap with. Actually felt normal when I was tapping. Snapon guy said sorry and replaced the tap. Said I should have checked their hi dollar tap with a gauge first. Maybe I should have, but I thought I could truck quality tools.

You talking about cleaning the threaded holes in the block? man! That what they make thread chasers for. Never use a tap other than to MAKE threads.

That was many years ago, and a rough learning curve. I have the ones now like frogman posted now. You would think that if it could cut threads, it could just clean them out too. I had done it many times without fail. Probably been alright, but the tap was labeled right but the threads were metric.

 I have part of a set like that,  I Buy them as I need them.

Didnt get much done, degree'd in the cam was going to put the heads on but found one rocker stud was bent so that is in the machine shop for a day or two

Since I dont have the heads on I rotated the engine clockwise with the dial indicator on the deck till I got the highest number before going down once I came back on that number I set the degree wheel to 0

I didnt have a solid lifter so I used a old one flipped upside down. I placed the dial indicator on the edge (it was a bear to get the angle just right)



I did the degreeing at least 4 times to be sure it was right

After finding the highest point and zeroing the degree wheel and rotating the engine backwards .100 this is what I got at .50 going forward (clockwise) 48 degree's



Going forward past zero than to .50 I got 164 degree's



Total is 212 divided that by 2 and got 106 just where it was suppose to be

One thing that took forever (since I was trying to use my old memory ) was putting the chain on I did it the way I always did the two dots line up on the bottom. Well since I am teaching my son the "correct" way of doing this I pulled the Haynes book out to show him and it shows the cam one should be on top. That had me stumped but after messing with it and a square for about 20 minutes to get it perfect I rotated the engine and the two dots lined up on the bottom. Not sure why Haynes doesnt do it that way it is so much easier.

Unfortunately I have not worked on any vehicle for a while
Had to redo the Kitchen and Living Room so I can get a Garage this year (Wifes Rule )
Now that the kitchen and living room are done I have reinjured my shoulder (get the MRI results tomorrow) so I am pretty much one armed now ..

Every thing is now officially on hold


Going in next Friday to have my shoulder done

Rotator Cuff Tear and (dont know the name ) a ligament from the top of the shoulder (its what keeps the shoulder in) to many technical words I cant remember

Looks good. Your the man to build it in the kitchen, there is no way my wife would let me do that.

Kitchen? I saw the beagle and thought he was in the doghouse already!
