Rocker geo, hoe does this look to you guy's Options

[toon1]

so far the liift is good, cam card say's .426, I've got about .428.

Here is a pic. with the vave at half lift. Seems a little off(leaning back) to me.

Keith,

YOU WILL HAVE TO START OVER ON YOUR GEO WITH NEW CYLINDERS.

DON'T CUT YOUR PUSHRODS YET....!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Yo, if the cylinder heights (lengths) are ANY different from what you are using now. (and it will be different)

Your engine will either shrink or grow with different cylinders. Therefore different PR lengths.

By the way. Since you are getting P&Cs. Here is a notion for you.

I hope the following makes sense. It is difficult to write what I see in my mind and on the bench.

Check the length of the new cylinders for length. Write that measurement down. If they are different lengths. Machine them for equal INSTALLED length.

Else your back to odd ball GEO issues.

Now mock up your engine to make sure it all fits correctly.

If your cylinders are EXTREMELY close in length. And your GEO is still wacky. It's possible your cylinder registers are collapsing. Thats the area of the block where your cylinders sit.

Thats is a somewhat common problem for the POST 1973 2.0 cases.
I think the date is right.

I learned this data from Jake Raby over at his web site. I hope I have accurately stated it here.
He has taught many of us how this all works. Thats a grateful plug for Jake.

SO: Just for shits and grins. When you pull your cylinders. Find a dead nutz flat steel and see if you can find any depressed points on the cylinder registers.
X and Y this area and use a feeler gauge to check clearances. You should be able to eyeball this area if there is any demonstrative depressions in the block.

If it looks depressed from the outside of the register to the innermost of the register. Fix it.

If so. You will have to pull your studs and have your case machined flat. (Unless you have already done so) And hope the problem doesn't repeat itself. Or toss the case and start anew.

If you have this issue. And you don't rectify it. Your PR lengths MIGHT be all over the place. And your rocker adjustment will change for no known apparent reason. And the propensity for the heads to loose their torque settings is possible.
(Block is shrinking)

Maybe I am giving you too much to think about. You block probably has no issues with this..... Then again... While your there........

Thats just the way I am about these engines. And I don't know shit compared to some others. Yet I have checked one of my 1.8 blocks and one of my 2.0 blocks and found they had this collapsing problem. Not bad mind you. But enough to possibly build a very expensive boat anchor if I didn't address this possible issue.

If there is any other way I can help confuse your build.. Please ask.......

Measure...measure....measure. Mock it up as many times as you have to and make it all fit right.

Cheers,

Clayton
