Now I'm noticing a debate never thought it was to come and it is about the HP exhaust manifolds... which I think is CLEAR all magnum engines were with them.
My main concern is it seems the 335 hp 383 is MORE MAGNUM than the other LOL.
And per the mopar parts catalog, the 400 magnum got the same camshaft than the 383 335 engine, being a lower performance engine

then there is a superseded number for it, 4071002 camshaft one of them I have it NOS on its original box, and is purple. I vaguely recall that number, it was a newer "smog" cam, same lift and duration but altered timing events. Robert

Specs are 383 2V, 330HP 4V, and 350HP 440 256°/260° .425"/.435"
335HP 383, and 475HP 440 268°/284° .450"/.458" I missed this post! Thats sounds like the dealer databooks says, but DC book seems to be slightly contradictory So, any 383 4V is a magnum still with standard cam and springs, and all got HiPo exhaust manifolds. But the 335HP is a magnum "plus" And any 400 4V is also a magnum BUT they got all the "high lift" cam, still with the lower compression rate. LOL

335HP 383, and 475HP 440 268°/284° .450"/.458" So, any 383 4V is a magnum still with standard cam and springs, and all got HiPo exhaust manifolds. But the 335HP is a magnum "plus" No. The 383-4 335 horse was introduced in 68 with the Road Runner. The difference between it and the 330 horse assembly was, basically, it used the higher lift cam and springs introduced the year before in the GTX and Coronet R/T. The carb was different than the 330 horse as well as the 335 was intended to get a windage tray. The 906 heads were used on all 68 big blocks. The springs were different with the 335 but not the head casting. As Dan stated earlier, there are no HP exhaust manifolds. There are two and 4bbl manifolds. When Dodge brought out the Super Bee mid year, they used the 335 horse assembly and called it the Magnum. The 335 horse variant of the 383-4 was used from 68-70. The applications changed each year. In 68 only the RR and SB without A/C got the 335 assembly. In 69, any B body with manual transmission without A/C and the RR or SB with either transmission and without A/C got the 335 horse version. Any 69 B body with A/C got the 330 horse. Any non RR or SB B body (Charger, Satellite, Coronet) with automatic transmission got the 330 horse. The 1970 applications get a little more convoluted with the use of the 335 horse in B and E bodies. However, there was a 335 horse assembly available with A/C in 1970. Properly and originally, the term 383 Magnum refers to a 68-70 Dodge with the 335 horse version. Dodge did use the term Magnum on other engines after 1970. So.... 1968: 383 Magnum in Super Bees without A/C. 1969: Manual transmission B bodies without A/C OR a Super Bee with either transmission and without A/C. So no 69 Charger with A/C or automatic would have the 335 horse Magnum.

My 69 383 4bbl A/C car has duel exhaust,with what looks to be factory "H" pipe and hangers and mufflers. And I now think I figured out the yellow crayon 68 written on the front of my pass side valve cover is not a 68 it is an 899 and one 9 is gone and its written upside down. I will now have to go see if the pipes and mufflers have any numbers on them so I can figure out this semi-mystery!!!
Also do 383HP MAGNUM ROAD RUNNER 335Horse engines use the same pistons as 383 330horse pistons, or do the 335horse motors have valve pockets in them? Could you put a "RoadRunner/Magnum" cam in the 330hp 383 with 2bbl cam with out causing any damage? I know my engine(330horse) the pistons almost have a positive deck height at TDC. These guys are probably more knowledgable than me, but I don't think there is such a thing as a "factory H-pipe." Just FYI since you are talking about swapping a cam nobody will ever see for originality...
