sleeve a block

[Toms70Duster]

I have a '72 340 block that I got in a trade. It had dropped a valve and punched a hole in the cylinder wall. I was thinking of making a stroker out of it. It's 20 over. Would this be possiable by putting in a sleeve? Would it be strong enough?
Thanks,
Tom

Tom,done properly it will be fine my 340 block has 1 sheelve in it now and i'll be having another sheelved,because of rod bolt damage..its cheaper for me to have it sheelved then pinched to 30 over, then boring it to 40 over,and having to get new pistons by the way this is my 416 block..

Yup. Use a shop with modern equipment and it's fine. Sonic test the block... you may find you need more than one anyway.

Sleeving is something that is even done to new motors from the factory. That technology has gone a long way. I'd do as suggested and sonic test it, and maybe sleeve them all back to stock.

sleeves are sometimes thicker.

Old nascar guy's would punch all 8 out to sleeve them for thicker/consistant cylinder walls cause they would make more power=stay rounder and....don't forget to season it or cook it good to get it cycled out so they don't move around.

The next time you are at the track and a Funny Car or Top Fueler goes by so fast you get a whiplash trying to follow it, they are doing it on 8 sleeves.

aluminum blocks is why.
