If you're concerned with spending $1200 for a rebuilder Chev Big Block, consider this... A complete, driveable mid-70's Caddy can be found (check on EBAY) for around the same cost, and you get not only a complete, running engine, but a useable GM T400 transmission for the same price. You can pull the engine, trans and whatever other serviceable parts you need from the Caddy and drop it straight into your little Chevy sedan on a long weekend!

Of course, if you're going from a stove-bolt 6 to a big V-8, you're going to upgrade the brakes, suspension and tires to handle the extra weight and power of the new engine.

That's where another advantage of the Caddy engine comes in... The Chev Big Block started out life as a heavy truck engine, and the cast iron block weighs a TON! Of course, the aluminum engines are lighter, but you're not going to find one of them in a salvage yard at any price!

The Caddy 425/472/500, on the other hand, was designed and built as a car engine, and the complete engine weighs only a bit more than a Chevy small block.

Less weight means better handling, better brakeing and better gas mileage for your daily driver.

Good Luck with your project, whatever you decide.
