340 Engine Shake

Ok, we are on the same page. What I’m telling you is a sleeved block (done correctly) will be BETTER a than a block that isn’t sleeved. Simple as that.

It may be counterintuitive, but it’s a fact. That’s why I said sleeve it and move on.

BTW, there isn’t an aluminum block out there that doesn’t have sleeves in it. All of them. The sleeve materiel is better than the original block is.

I agree with you = the only Caveat is it is easy to do one or two sleeves and keep alignment accurate.
I only know a couple in the western states I would trust to do 8 straight
and I would set me back $2,000 to $2,500. Perhaps $3,000.
A single thick sleeve cost me $400 to 500.
Maybe I am too fussy about who does this stuff for me.
It seems to have gone up 1/3 this year!
