Yes, F is car-model-year 1970; I believe 69coronetRT is stating the engine was assembled Dec. 19th, 1969 - which would jibe reasonably well with the SPD of Jan. 21st, 1970 for the whole car. Engine build-dates are actual, SPD's are approximate/estimated. Car could have been built before the 1/21 SPD (or, on it...or, after).
Yes but some do not work or stopped working.
It’d be the same for C’s Ray. In other words if this was a U code ac car it would have 116 on the sheet. I just don’t have the numbers for the 350 horse LP 440’s.
Casting number(s) (pictured) really aren't relevant to what I think this thread is trying to do. The partial-VIN would be stamped into the opposite (Passenger's) side of the block to tell whether this particular engine was original to this car. The *103* of interest (the last three digits of the engine assembly's part number xxxx103) on the broadcast sheet will not appear anywhere on the engine.
Uhhhh.....my C-Bod is 118, and I'm absolutely sure it's a matching number U code mill.
The engine assembly number is a three digit code that appears on the Brodcast sheet as well as on a 69+ Lynch Road fender tag.
No offense intended - mistook pics as from OP for "decoding" numbers
honestly no offense taken ... but thanks.
Yeah, I'm with ya, because most of us Mopar aficionados are pretty familiar with the B and E-Bod codes, since those are the performance cars that get all the attention. But when I got into the C's, I realized that my prior knowledge about codes didn't always work. Fender tag stuff usually works across all the lines (D32 is always the HD 'flite), but BSheet numbers sometimes do, sometimes don't.
"4160" is the family of Holley carb. 4bbl, vac secondary, metering block in front, metering plate in back, single inlet front bowl with the balance tube for the rear bowl. Similarly, 4150s had a rear metering block and could have race bowls, did have a single fuel inlet for EACH bowl (known as dual inlet) and no balance tube. The R4749-3 specified the "guts" of the carb, as in jets, metering block and metering plate, choke calibration, as in the whole assy. for a specific engine and model of vehicle. Given the "-3" in the carb number, I suspect it might not be the actual as-produced carb, but a later model replacement for the orig carb, possibly for a year or so later model year. The FSM is again the resource for the correct as-produced carb number. As is the Holley Variable Spec Manual.
The difference between a 116 U and a 118 U could be simply exhaust manifolds - not sayin' that IS the difference, just that it's possible.
Yeah, good guess. It's the little things!
Well obviously now that info is posted..
