340 General Rebuild Info- Cam Recommendations
Guessing these are the "J" markings although they look like big "U"s..... Sooooo, actual valve size remains TBD!
U O J Z castings are pretty much the same.
There is a part number on the heads. IIRC that will identify what they originally had in terms of application. Have to remove the covers to see those.
Appears to be original carb, but not sure where numbers are and not worried at the moment...I know it needs an accel pump. Dist also appears to be orig. I can see tag on front of it, but can't get in to read what the numbers are
That's good. Tag on means its probably not molested.
It has this dual inlet "no snorkle" air cleaner on it. I would expect 71 to have heated air to the carb in CA??? So guessing that this is something that the prev owner swapped in?? I have more pic's of mystery items that I will ask about in the engine compartment but will save that for next post. Gotta go finish cleaning up a wheel rim....ugh!
Many of your questions can be found in the factroy lit. Links below
Decal in trunk "says" Sure-Grip......but stickers only cost pennies to install..... Can't get under car easily at the moment.....cats let the air out of one rear tire.....and I can't put my hands on the other set of rear gears that "I think" came with the car.
Once you jack the rear up, turn a wheel. if the other moves the same directions, it has an LSD.

The 1970 Hamtramck Registry Library Page (1970 - 1974)
Sales Lit, options, and corrections to Service Manuals (TSBs) plus a variety of other material.
Online Imperial Club (OIC) for Imperial, Chrysler Imperial, and Chrysler New Yorker Brougham Enthusiasts
A very complete descriptive index of the Master Technicians Conference
https://www.web.imperialclub.info/Repair/Lit/Master/index.htm
However it has some broken links since changing from .org and .com to info.
www.mymopar.com also has the MTSC booklets and filmstrips and movies, but not as good an index.
So use the two websites together.
mymopar also has Service and Parts manuals available as digital downloads (pdf).
So that will get you going even if you prefer to buy a paper copy.
