My guess is the 392 or the 426, if were talking Chrysler Corp designs.

here's one from over on moparts lol. not mine. some of the guys over there have 605 c.i. hemi strokers. this one only 588 c.i. i guess that's pretty big size
so the biggest ones "built" are made by racers and street people not by the factories. 605 c.i. = 9.9 Liters
this 588 c.i. is 9.6L

I misunderstood when you dais biggest, I though physically. Do you mean displacement?
I would say the largest production Gen 1 would be the 392. The largest production Gen 2 is the 426, and the largest production Gen 3 is a 392. (6.4 litre). tmm

Yeh, heh.........I think we need some "rules" to the question...........
You talking about biggest factory hemi, or aftermarket crate, or "no limits" stroked?
You talking early, Dodge, Chrysler, Desoto, or 426 based or 3G?
So far as I know the 426 based design has the potential for largest cubes. This is limited by the centers on which the cylinders are drilled so far as bore. In other words, even if you built an aftermarket block with siamesed cylinder walls, you can only bore them so big.
Stroke in an aftermarket block which follows the original design dimensions, that is distance from cam to crank centerline, is quite simply dictated by the internal dimensions of the block and how much "you think" you can grind clearance out for a great big long stroke crank before you separate the bottom end from the top end.

If you're talking the largest Hemi headed engine, no other "rules", Sonny Leonard builds a Chevy/Hemi, just under 1000 cubes. Got 100k or so for one?
