Bart,
I wonder if there is anyone out there that has had experience with O-200 push rod lengthening. I'm aware that we can buy various lengths of rods but they aren't cheap but I am. Question ( not certified engines ) would there be a problem pulling the ball end out of the pushrod and putting a spacer cut off an old piece of 4130 pushrod tube? The spacers could be cut about .020-.030" thick with a lathe. (the shank on the ball is app. 1/2" long and is a tight fit to the tube).
Perhaps this is dangerous in that these spacers might break but I think the pressures on the spacer would be minimal.
Thanks in advance
Robert

Why not just cut a new 4130 tube to the length you want. (Experimental of course}.
Sully, Yes I will order some, it'll probably take 3-4 weeks to get here. I just thought some one that knows what they're doing might say yay or nay to the idea of adding a spacer.
Thanks

Let us know. I always need one or two longer ones. An outfit in Colorado sends them new at half price - markup must be wild on these.

I've heard of cutting them and putting them back together but not adding a spacer.
On close examination I see there is a taper to the shank on the ball, it may be a step taper, I can't really tell with my crude equipment, looks to be about .003-.004" so I think the right thing to do is to replace the tube and not add spacers.
Thanks everyone for your input.

Hi all,
is there any chance that one of you with a 7KCAB could post pictures of your engine installation and firewall setup? Also, maybe of the inverted fuel tank installation.
I purchased a project that was intended to put an IO-320 with inverted fuel and Christian Inverted oil system on it...it’s an ECA by birth. When I am done if all goes well, it will be a 7ECA/KCAB. I am basically looking for the pattern and Pictures with more fidelity than the service manual and parts diagram. Thanks.
