402 Big-Block Rebuild, Part 2 - 1967 Chevrolet Chevelle SS

In our second installment, we hit the machine shop, and get our 402 and all its parts and pieces ready for reassembly.

In the last issue, we covered the disassembly of the 402 big-block out of our AMD 1967 Chevelle. To recap, the motor had been pulled out of a salvage yard, given a quick and dirty refresh so it would run, then repainted and dropped between the fenders of our SS396. We knew it had a cracked piston in at least one cylinder, and overall needed a full rebuild so we could drive the car without fear of it grenading.

With the proliferation of crate engines today, ranging from budget minded to out of sight, some might be wondering why we're even bothering rebuilding this "small" big-block. There are multiple reasons. First, this is the engine we had. There are a lot of readers out there that don't have the budget for a crate engine, or just want the satisfaction of building what they've got. Then there are the class racers who have to run a stock displacement engine.

Second, just because a big-block doesn't have gobs of cubic inches doesn't mean it can't make great power. Along with that, the shorter stroke of the 396/402 gives this engine an easier ability to rev up fast, much like the difference between a 327 and 350 small-block. Third, we just recently did a build of a 496 big-block, so why do the same thing over again? And lastly, we just have a soft spot for the underdog.

After disassembly, we hauled the block, heads, and crank along with all our new parts to Tommy Eufemia at Bad Attitude Engines in Morriston, Florida, to be cleaned up, machined, and prepped for reassembly by Jason Rollins at Rollins Automotive in Gainesville, Florida. On arrival Tommy looked over everything, then set about the process of getting our Rat back into fighting trim.
