Really? I just went out and put a couple calipers on the It's cylinder bores..... all 4 were virtually identical. I have an older US measre caliper and reads 3 47/64ths..... the digital reads 3.748". I would have expected them to be OVER 3 3/4". Do I need new glasses, or is this the norm?
Might be one of those in-between motors... # 1058693, but had cast iron pistons.
You are likely reading where the ring does not travel with calipers
True....silly me ... duh.... My calipers don't reach any further. Both are only a 1/2" long or so. Will look for a different method. I should gave SOMEthing i can come up with, and remeasure.
Thanks foot the correction!
Dennis, you need a set like this to measure the bores. Take measurements at several depths and planes. https://www.amazon.com/16-PRECISION-TELESCOPIC-BORE-GAUGE/dp/B000I8NDAS/ref=sr_1 _1?s=automotive&ie=UTF8&qid=1492653074&sr=1-1&keywords=Telescoping+Gauge
Sounds fair enough... ordered!
I thought I had a set of scissor calipers, I could then re-measure... but guess not. Good set to have, anyway....
If you're going to be at our Casual T's Crank-Up Dinner tomorrow, I could bring my bore gage with me for you to borrow. Let me know SOON though!
Yes I am! I did order a set though... but don't know when they will be in.
A Les up onb Lapeer offered a head too... so I can do some testing.
If my memory works I'll have the gage with me.
If it works as good as mine .... good luck with that! LOL :-)
Well, I did remember. Then I got sick and didn't make it, as you know by now. Still available for borrowing if you need it. Let me know.
If you don't have an inside micrometer, this method will tell you whether you have taper in the cylinders. Put a ring at the bottom of the cylinder and measure the end gap with a feeler gauge. Move it up half way and measure again and then move to the top and measure. The gap should be the same at every level. If it differs, divide the difference by 3.14 and you will have the taper.
