Wet Sleeve Follow up

Dellbertt · Nov 6, 2009

I don't remember the old 327, 283, 409 or 396 Chevy's having sleeves.
Do all engines have sleeves or do some piston/rings ride directly against the block.

You are right the 283 327 396 409 427 did not have sleeves. These were my favorite engines when I was young.

The little 60 c.i.d motor in the Cub is one of the motors where the bore is machined directly into the block.

In my experience, most automotive engines are of that type, not sleeved. Depending on whether there is enough meat in the block, some such engines can be bored out to take a repair sleeve (necessary when one can no longer get pistons or rings of the correct larger dimensions to fit a rebore), a thin walled sleeve that relies on the metal in the block to support its sides against combustion pressure, same general concept as a dry sleeve.

Very few if any car and light truck engines have or ever did have sleeves. The big truck diesel do. The reason car and truck engines don't have them is because they are pretty much made to be throw away engines and where made to only last a few 100 thousand miles at best

The Ford flat head v-8 had a dry sleeve. Had a '37 coupe, first car. Up graded to a chev, broke crank shaft and block 6th day I had it. Been wrenching ever since.

Most tractors and heavy trucks will have either dry or wet sleeves. Most cars and light trucks will be direct bored. I believe this is because the first ones are intended to last forever and have the sleeves replaced, while the cars and light trucks are disposable.

taking about those old G.M.engines i saw a 283 that was bored out .080 , but i dont know how long it lasted as those wall must have been pretty thin with that much meat being taken out. pretty common to have any one of these bored out .030 or.040 and they sure were not throw away engines.the throw away engine was the 350 olds motor converted to diesel, just too light and did not stand up.

You can bore the 283 .080 and not have any trouble. I had one and it got tested. I also tried one turning nine grand not pretty.

I still have a set of valves for the 283 engine.

I bored one out to 4 inches (.125). That made it a 302. High dome pistons & a race cam with solid lifters. I ran it for years until I sold it. It still outlasted the 60 body & was put in another one.

Way back in fiftys and sixtys have seen several small block Chevrolet V8 engines that had one or more sleeves in them. When block got badly scored they would bore them out and press sleeve in, do not know how well they held up.
