Best Engine Blocks in 2026

Any garage enthusiast rebuilding a classic Chevy powertrain needs this heavy-duty steel cradle to prevent heavy iron blocks from becoming dangerous floor obstacles. This JEGS stand is built specifically for Gen-1 small blocks and big blocks with side motor mounts, though you should note it won't accommodate newer LS engines. The construction feels incredibly solid, supporting up to 750 lbs without feeling flimsy, and the black powder coat provides a professional finish that resists shop grime. I love that they actually include the necessary storage hardware, so you aren't hunting for bolts mid-assembly. Moving a heavy engine across a concrete floor is surprisingly effortless thanks to the 3-inch steel casters that swivel a full 360 degrees for total maneuverability.

Most mechanics settle for cumbersome, static supports that make engine swaps a logistical nightmare, but this Speedway Motors rolling cradle turns a heavy lifting task into a mobile operation.

A standout feature is the built-in hardware storage, which keeps your engine mount bolts organized and prevents that frustrating search for lost pieces mid-build. Just keep in mind that it won't work for 1955-1957 265 and 283 SBC engines due to their lack of side mounts, but for most Chevy enthusiasts, it is a massive workspace upgrade.
