I need to mount everything and check the starter to flex plat fit.

Looks good so far. Nice beefy looking part. Good luck with the project, I'm sure you'll run into a bunch of little things that need to be "adjusted".

On the parachute mount
Check the depth going into the adapter with the converter, mine only had .030 . I took .100 off
The adapter so the converter had more clearance . I checked it with some play-do

Time for some RobbMC adjustable offset bell housing dowels to correct this twocents scope
I'm thinking less than .007 total run out like we shoot for on stick shift scatter shields scope up

I think the biggest offset I can get is .015 and to pull the 1's in the engine all I have is some visegrips so I hope that works.Moving the bell .015"I don't think is going to effect the starter much.

.032 off center? - I think you better double check your measurements again - I have never seen one out that far

How are you centering your dial indicator on the Crank??

I didn't.I measured for the low spot and 0 the dial.I still have it set in place to measure today but I am confident it is reading okay in the small steps I am turning it and the angle is small.

You have account for indicator sag when doing it the way you are. When you are on top it is falling away and when you are on the bottom it is falling toward. It won't be .032 but there is some.

OK - I got you now- divide .035 by 2 and your number is .0175 - a .015 offset dowel will put at .002 which is considered perfect for high RPM - if you get between .05 and .010 you are in the good range for what you are running

You need to do 4 points every 90 degrees so you know what what way it is shifted

Hey Mike if you need a rock solid dial indicator mount that bolts to the crank flange you can use mine. I had it made strong so I could get my bell dialed in without the indicator moving around. Let me know and I can meet you somewhere and get it to you.
