i was wondering if anyone has put a short deck chrysler cam in a desoto motor? is it even possible? i know that the tall and short deck cams are different even between chryslers thanks
I don't think it will work --never heard of anyone doing it. Call Chris Nielson in Utah , He will know if it is possible (801) 451 7745
the only differences I recall between tall and short deck chrysler hemi's is the way they're mounted up front and the fuel pump eccentric, which you can get a kit for to correct when using a later tall deck cam in an earlier short deck motor...I doubt the Desoto cams and Chrysler cams will swap...there should be a few places that'll regrind stock Desoto cams to different profiles...
The desoto has different bore spacing than a chrysler and therefore the bearing positions on the cams are different. I assume what you are trying to do is get a better performance cam than what you can grind into a desoto stock cam. The desoto was ground stock on something like a 118-120 degree lobe seperation angle, and all that you can grind into it is about 114 degrees of lobe seperation. You are also lift and duration limited simply because there is not enough material there. I found an old billet one-off desoto roller cam. I degree'd it and it is huge...300+ degrees total duration (I have it written down somewhere). It is also ground on a 108 LSA, so I figured worse case if I don't like the grind I can regrind it. I haven't run it yet. If you need a stock cam to regrind, I have a stock 291 cam in good shape I would let go cheap. Otherwise you need to find an old performance cam, they are out there. Also most guys switch to the later cam snout, I think it is 341 on??
i have a 291 but i'm thinkin that maybe a 341 or 345 cam might be a better start for a regrind being that i intend to raise the compression to where those engines were stock? or are those motors tall decks? thanks again for the help
I'd be interested in the 291 cam. I think it can be machined to be the same as the '56 and up cams, so I could use it as a regrind in my 341. I'd have to let hemispherical pass on it first though.
i was wondering more so if later model mopar small block cams would work. at least as a blank anyways. the way i understood it the desoto blocks were the basis for the polys and later on small block engines and share quite a few numbers and geometry with them. something to ponder anyways.
1. what are the angles? 2. I believe this is true of the DeSoto tall (330, 341, 345) vs. short (276, 291) decks and Dodge tall (315, 325) vs. short (241, 259, 270) decks as well?
Yer name is "HEMISPHERICAL" and yer askin this question ????? HEMI cams are not interchangable from each other at all .... PERIOD ! Dodge fits Dodge .... DeSoto fits DeSoto .... Chrysler fits Chrysler Tall decks & low decks cam are different from each other. If you are not sure of anything here, dont try and get crazy ... Run what is suposed to be in the engine.... Make your build easy. BUY THE CORRECT PARTS FOR YOUR ENGINE !! If you need to ask a simple question such as this, You are not ready to start doin crazy stuff with a hemi. Im not bustin yer balls, Just givin you a word of advice
My Dad owned a 291 hemi. He had to have the cam built up and reground, couldn't find another (new) one.
yeah i have more modern hemi knowledge i.e. blown alky and blown fuel. the old stuff is new to me. i just a cheap ass bastard and would like to avoid thowing money away if i can find a hotrodders solution i want it right and i was nervous about the whole cam regrind issue so if another would have worked i would have preferred it. i appreciate all the info though; thats why i asked
Nope, just the 276 & 291 DeSoto cam in the low deck. There is a guy in Palmdale who has or had a shit load of N.O.S Isky cams, i bought one for a 291 from him. his name is Jon but i cant find his # .. but if you look up on E~Gay for "VINTAKES" ... Thats the guy Good Luck
i bought a cam for a red ram 241 from him, nice guy, good service. i need to call him back and ask what kind of lifters i can use on this cam. i understood most the early isky grinds were soft and required special lifters. can anybody here back this up? and what about my other question up there?
Nope. The late A series Polys shares almost nothing with any of the earily Hemi's. The earily Polys are block down identical to their corosponding Hemi's(pistons are different and thats it)
