Inside Micrometer
#1
I am getting ready to install my 351C crankshaft...just waiting of the engine paint to dry.

I was just going to check it with plastigage, as I did for my first rebuild. But then the 385 forum guys kind of scared me into thinking I should get a guage.

So I looked for a gauge and went ARE YOU KIDDING ME????

Anyone have a good source for an accurate inside micrometer good to 3.5"?

Thanks.

How did the paint come out? Did it dry correctly this time?

Plastiguage will work...if your worried about egging, check all around the journal.
check pawn shops and flea markets...I have seen some for a good price there.
Too bad your in a third world county as I have a great inside set you could use

With practice this may be an alternative, if you have outside micrometers or dial caliper. http://www.sears.com/hft-telescopic-engi...ckType=G21

I found a good set on Amazon.com. I also found a dial indicator and a cam bearing removal tool.

I am getting ready to install my 351C crankshaft...so the inside bearing diameter.

I have looked on eBay, but I need accuracy to .0001. Almost bought one without looking very close...got into lots of trouble in my younger years that way.

I believe that is

Crankshaft= 2.75" less the .0010 taken off the crank
Crankshaft fine= 2.74" (I have a mic for this)

With .0015 to .0025 journal clearance= 2.7385 to 2.7375.
