Interesting how the term “Stroker” has evolved from a Guys name, into an Internet buzzword.

Not a “drop in”. .200” must be removed from the Mains.

The “magic” is in the perception. “383 stroker” Doesn't it just sound impressive?

So impressive, that its shortcomings go unnoticed.

........ These are completely different than the Chevy motors, so Chevy ways of building things don't apply .........

The same laws of physics apply to both.

........ the BBO uses larger bearings than the SBO ........

Just as the 400 uses larger bearings than the 350.

........ theoretically you could have a BBO crank turned down to fit an SBO block ........

It's been done, more than once. Solves the “bearing speed” problem, but creates another, with the “poor” rod/stroke ratio. Same problem that was designed into the 400 (so, to the 383) Chev.

........ easy alternative is to use an Olds diesel block, which already had BBO-sized bearings ........

Same main journals, same bearing speed. Same “rod angle problem.

........ you get into things like custom rods and pistons ........

As I said before,

it can easily be done with off the self parts.

........ The better question is, why bother? ........

To be different? I don't see a “383” as being different, but the number certainly draws a lot more attention than my 437.

........ however, swapping a 330 crank into a later 350 or 403 gives you a forged crank ........

The term “forged crank” can also impress an audience.

........ 403 or the 455 (or 425 or 400) swap ........

Cheap and easy, with good results.
