I've been looking for a good running 68-69 383 4-bbl engine to get my Challenger running. All my big blocks are gone save this 400 i have, but its a stick car and i'm not gonna chase down and buy a flywheel for a 4:1 smogger. Seeing as now that i need one, i cant find a good running 68-69 383 4bbl engine to save my life. I want that specific model for its higher deck height. I have some nice shaved 516's and could make some good compression, and depending on what i've read being true or not... possibly some hokey quench too.

Anyways, a friend has a 67 383 2bbl engine that i can borrow (till i find or build an engine... its not like i'm gonna blow up a 383). Other than being a low-comp engine it fits the bill. What i want to know is are the 2bbl pistons in 67 different than the 2bbl pistons in 68-9? The 67 has closed chamber heads and the same rated CR, so i wonder.

Also, why the two different engine in 67? there was a 2bbl at 270HP and another at 290HP. The 4bbl was 325. Another book sees only one 2bbl engine... the 270HP... which seems low for the year. What would the differences be between two different (same year) 2bbl engines...???

Okay, I am going from memory here so if it turns out to be partially or completely wrong, don't go beating on me. In 1966, my parents bought a new 1966 Chrysler T&C wagon. IIRC in the owner's manual (when owners manuals still had some technical details) there were two 383's listed, the 270 hp 2-bbl and a 290 hp 2-bbl version. Again, IIRC the difference was the 290 hp was a higher compression premium fuel motor.

If someone has a Chrysler owner's manual from 1966 they should be able to either verify or dispute this. I have a 1967 Plymouth salesman's book and it lists only one 383 2-bbl motor.

Only 1 2bbl 383 offered by Plymouth in 67, that I know of. It's a 270 hp, 9.2:1, w/ 516 heads. Yes, the pistons changed in 68 when they went to the open chamber heads. My Satellite had one of these motors originally. With nothing more than a cam, set of headers, and intake / carb, that old stock 383 pushed my satellite to 13.7's!

I have a 65 & 66 383 2barrels in the corner of my shed I would part with. I fired up the 65 once after I got it & the 66 I had running this spring. My buddy has a 69 383 2barrel that had 66k on it when when I pulled it out of a newport I was going to demo. I drove that car home. Ran nice. It was oiled and gets rotated a couple times a year. We are in WI. PM me for more info.

put the big summit cam in there while your changing the intake onnly like 120.00

holy bleep , not one "ov" in any of those posts

300S could be had with a 383 . i had at least 10-12 chryslers that were 300s and most has 383.
