If your going with a V8 I wouldn't sweat it.
The side to side play will make your dizzy fire in a jumpy fashion you can see watching in with a timing light.
Did you consider the berrymans chem dip to try and remove the carbon?
My line on the V8 seems ti have withered. So I am picking up another 258 from a member here.
It was running when he pulled it from a Jeep he parted out a while back.
At least that much is known about his engine. My spare - no idea.
Hopefully this one will limp me along until I can do a proper rebuild, or something.
Didn't consider the Barryman's because my initial leakdown test (which I am not 100% confident in) seemed to indicate a blown head gasket between 1 & 2 as well as leaking valves in all cylinders. Maybe I screwed up the test. Had never done one before, so who knows?
try another leakdown test with the VC off so I can verify the vales are closed in each cylinder when I do it.
But right now, I've just had it with this engine.
It's obviously gone beyond my experience.
