Default 346ci vs 350ci

I've noticed several aftermarket companies imprint "350 cubic inches"on nameplates for underhood and for the dash. It's a "346", not a "350". They are different engines.

Anyone know of an explanation for this?

^ People are stupid.... they like the 350 "ring" even though it's a 346. Me... I'd never put any sort of "350" badging on mine.

Just like a 302 is really a 4.9.... but 5.0 sounds way cooler.

350 is marketing and that sells cars. Like you drive torque, but sell horsepower..... so I could never understand why chevrolet originally listed the LS1 at 345 hp.

To me, 346" is way er than 350". It distinguishes the LS1/6 as an advanced tech engine when compared to the old 350".
I thought about getting one, but couldn't find one with 346 on it. One even stated "TPI" instead of "SFI". And, being sold by some Forum vendors. Seems like they would know better.

My .44 Magnum shoots .429 diameter slugs.

My .38 shoots .357 bullets.

But .357 Magnum sounds mo' phat ***** bichen than .38 Special.

So maybe my motor is a 346 Magnum!


Isn't marketing great

But, rounded to the nearest inch it would be a 428". The bad thing there is it would relate to a FORD! Marketing.

I predict this thread turns gnarly in two more posts or less now that we've started talking about things measured in inches that aren't really the size claimed, like 1" iron pipe isn't one inch, etc.

I'll jump on this "wagon" with this fact on over bored 283s in the day were called 301s, in '69 GM built a factory 302 that was the same bore and stroke. Both engines were actually 301.7 cubes.

I put 346ci emblems on my car back in 98 and loved when people asked what that meant...

I don't recall seeing anywhere that Chevrolet/GM refers to the LS1/6 as 350". Always 346" or 5.7L. Only in the aftermarket have I seen 350", or by some people, erroneously.

Seems to be less common in the metric days, but if you'll go back and look in the 60s, 70's, etc. you'll see it much more. Usually just "rounding" to the next even number. The motorcycle companies did it too.
