360 vs 383

LOL .. i get it, although I might :D . I'm just saying, are both engines 100% up to snuff? Any updates on one vs the other? It's very hard to hold 50 year old vehicles to a standard of 50 years ago, so many changes between then and now. And were those changes equal? I guess that's why I said there is a lot of property there to cover, but I get your comparison.

i'd say they're on very equal ground.

the 383 is all OG and low-ish mileage. has a 70's holley 2bbl (prob off a 360!) and mopar electronic. that's it. still running (cracked) manifolds and a full dual two miles long back over the axle and kicked out the side with ginormous RV mufflers.

i did the rebuild on the 360 in the early 2000's and it got stock slugs .020 over, i forget what heads at the moment, but they're non-smog port regular *** 2bbl 360 heads that got a 3 angle, stock 2bbl manifold and a melling cam. i *might* have put thinner headgaskets on it, but i can't remember seeing as that i've slept since then. but other than that, nothing special. it was and always has been a work truck. so, it's still tight and right, runs good. same thing, mopar electronic thru factory manifolds, full exhaust over the axle kicked out at the rear tire.

the biggest difference between the two besides nine miles of exhaust pipe, is the gears. little boy is running a 8.75 with 3.55's and fat man is running a D70 turning 4.56's but the tire height puts them within the same realm.
