The week is almost over, and once again, Thursday has landed on our doorsteps. I don’t know about you, but my weekend plans are already made. If your away-from-work plans include a trip to the salvage yard or swap meet to score a “new” engine block for your project, we can help with that. No, we are not going to scour the yards for you, but we can help make sure you choose the right engine. Once again, we celebrate another editorial look-back, and jump into the way back machine to open the Power Automedia vault that houses our vast collection of articles and revisit another great informational piece.
In this Throwback Thursday, we’re taking a small jump back to September 2013. That’s when we put together; Chevy Engine Block Casting Numbers. Throughout the decades, the Chevrolet small-block engine was referred to by several “series”. It started as the Gen-I small-block, then the subsequent Gen-II LT, and then Gen-III/IV. After that came the LS, along with the current Generation V (LT/EcoTec3) engines.
The Chevrolet big-block was developed and used in the 1950s through the 1970s. Although Chevrolet had introduced its popular small-block V8 in 1955, it needed something larger to power the medium-duty trucks and its heavier cars that were on the drawing board.
This wide-range usage means that tens-of-thousands of these V8 were built. Once plentiful in salvage yards, finding them at a relatively lean price is getting harder to realize. That means finding the perfect block and knowing what your looking at is vital.
The original article gives a thorough listing of block casting numbers, and what they mean. For the true Chevy guy, the in-depth listing is a wealth of knowledge that is vital. If you’re looking for some insightful information that you can use while shopping for your next project engine, check out: Chevy Engine Block Casting Numbers. You’ll be glad that you did.
