MPN: 8B SL 44-323
The BRODIX 8B SL 44-323 is a steel replacement cylinder sleeve cut for big block Chevy engines built on the tall deck. It runs a 4.590-inch bore and sells as an individual unit, so engine builders ordering for a full block need to count cylinders and order accordingly. This sleeve is aimed at high-performance and racing rebuilds where a damaged or worn cylinder would otherwise mean scrapping a good block. Anyone shopping for new cylinder sleeves for a big block Chevy at a fair price will find this one straightforward to spec, since the bore and deck application are both fixed and there are no surprises in fitment.
BRODIX machines this sleeve from steel rather than cast iron, which holds up better under the cylinder pressures racing engines see. Per retail specifications, the sleeve measures 6.625 inches in height with a wall thickness of 0.081 inches, giving the bore the support it needs without overstuffing the water jacket. Outside diameter is listed at 4.711 inches across most sources, so machinists should verify the block counterbore against the sleeve before pressing. The 4.590-inch finished bore lands in the range many big block stroker combinations target, and the tall deck cut keeps the sleeve seated correctly in raised-deck castings. Builders sourcing matching hardware will also want to check our big block Chevy main caps and piston ring sets while the block is apart.
Reach for this sleeve when a cylinder has scored, cracked, or been bored past the limit of the parent casting and you want to save an otherwise sound tall deck block. Pressing in a fresh steel sleeve restores wall integrity and lets you go back to a known bore size instead of chasing oversize pistons. Because it ships as a single unit, it works for a one-cylinder repair or a full re-sleeve depending on what you order. Pair it with the rest of your rebuild parts in our engines and components section, and look at other cylinder sleeves if you need a different bore or deck height.
It ships as a single unit, not a pair or set. If you are re-sleeving multiple cylinders or a full big block Chevy block, order the quantity you need based on how many bores you intend to replace.
The 8B SL 44-323 is cut for a 4.590-inch bore and stands 6.625 inches tall, per retail specifications. It is designed specifically for big block Chevy engines built on a tall deck block.
BRODIX machines this sleeve from steel rather than cast iron. Steel handles the cylinder pressures of high-performance and racing engines better, which is why it is a common choice for serious rebuilds and re-sleeve work.
Wall thickness is listed at 0.081 inches and outside diameter at 4.711 inches across most sources. Some listings show a slightly different OD, so machinists should measure the block counterbore against the sleeve before pressing it in.
