383 stroke

[Mopar Fred]

I have a question I have read online and in engine building manual that the stroke of my 383 is 3.375 but in a direct connection 1970 bulletin that I have acquired says the stroke is 3.380. So I was wondering what it really is ?

3.375 which rounds to 3.38.

If you’re reading an engine building book that rounds numbers up (or down) that book should be used to light your fireplace.

It's listed a lot of places as 3.38, but the true stroke is 3.375. I mean......it's .005" difference. Kinda splittin hairs, really, BUT, when you're measuring machine work in thousandths of an inch, splittin hairs is EXACTLY what you should do.

Hey @rumblefish360 was your disagree to post 3 on accident or do you actually disagree?

Sure seems to me that stuff like bore, stroke, rod and main journals and clearances, should be pretty specific.
