You milled the squish? That is a fun job... After you are used to setting up and the indacating the jug it comes so easy. But first few times can be frusterating to get right. It really is a finess thing and knowoling your machine. Nice work!!!

Yup, milled the squish. Pain in the butt, I am getting better at it though.

This cylinder is way snug near the base

bore on this cylinder isn't round either

It's out of round at the bottom, further up in the bore seems ok. I have about .002 - .003 ring gap up there.

The narrow side of the jug at the bottom is between the trans. Once I get the piston by the narrow part. It shouldn't touch the skirts

So you think it will be ok?

Your #s are very similar to mine (w/o base gasket), but I don't have the fancy toys to do the mods you are doing!

Mine is 105, 121, 83.

I cut .060 off my base, you sure your numbers are accurate?

 

[MustangMike]

I've double & triple checked TDC, the exhaust and the intake. The transfer is harder to check.

 

[MustangMike]

My base gasket was .021, and when I measure where I marked the 1st Cross Cylinder compared to the second, the exhaust port is about .060 different, so I'm pretty confident I have the correct #s, even though this is my first time doing this.

 

[Deets066]

Cross cylinder #1 was 99-115.5-79
#2 was 99-116.5-77
Farmertech jug was 93.5-124-85

 

[Deets066]

All measures with gaskets

Cross cylinder #1 was 99-115.5-79
#2 was 99-116.5-77
Farmertech jug was 93.5-124-85

I think the Cross #s look much better w/o the gaskets. Mine had about .045 squish with the gasket.

Witchcraft and blasphemy

99 120. .0147" is 1°

that changes with crank angle, just saying

Have you ever got a 660 to 102?

I have a stock oem 660 cylinder with an ex dur of 160 no gasket. find a good one every now and then
