    Hey all! I'm trying to figure out what year my chevy 350 is. It's currently in my ratt rod and I need parts for it. I've looked online and couldn't find my model.

    Here is what I have:
    V0417XUA. I can't find ANYTHING on "UXA"

    Thanks

    In 1969 there is an XU in a C50 truck...the A might stand for automatic. I can't see how the year makes any difference when ordering parts though. When the parts man (normally Autozone...etc) asks me what year is the car...I make one up. You know the difference between a 1969 350 and a 1973 350 is? Nothing.

    I knew somebody would catch that.
     
  7. That is apparently the numbers off the stamped pad on front of the block. It would be a big help to have the casting number of the drivers side bell housing flange.
     
  8. Yea that's where you look^^^^^ and a lot of those 350s in Rat Rodz are actually 307s. :rolleyes:
     
  9. Best thing that could happen to 307!
     
  10. Numbers/letters cast into the block, in the back bell housing area either side (usually passenger side) of the trans bolt boss at 12 O'clock (This boss may not be drilled & tapped). It'll be a letter, then 2-4 numbers. Example "D129" this would denote April 12 1969 (April being the 4th month of the year, just as D is the 4th letter of the alphabet) 12 would be the day of the month, and 9 would be 69 (1969).

    or a 305....
     
  12. is the dipstick on the drivers or passengers side? are the valve covers center bolt or have perimeter bolts?
     

  13. In your post you say UXA and XUA. Since there doesn't seem to be any UX's, the only close match is as Black Panther suggests, '69 350 2 barrel 215 h.p. Only other possibility is you misread the X and it's part of the number leaving UA which is a 307,

    but the number is 4 digits, not counting the X, so that's not too likely.

  16. You are right, of course. I failed to notice that because it is obvious and I am getting senile.
     

  17. Took awhile

    It looks like you have the assembly date: V (Flint) 0417 (April 17) XXA (three letter suffix beginning with X usually meant over the counter [crate] motor). The assembly date number has no year. It is assumed to be the same as the model year the block was cast, but there were exceptions. The casting number is needed to answer your question.

    UXA is not in my MSA1 book
    XUA shows to be a 1996 350ci 210hp700R4 tranny RPO L-05 with TBI with a VIN letter K installed in a G30 van

    Just because you can't find a match on the good old inter-web doesn't mean you read it wrong. For example I have a 1968 302 Chevy . The only match I can find for it is a 427 stamping #. I can definitely tell the difference between a big block and a small block.

    1996 eh? Never thought of anything that new....probable...funny how I consider 1996 as "new"..and its near 20 years old. My experience with counter exchange ..warranty or over the counter motors is that there is an additional stamping to that effect. In other words...the assembly code would be the same as what its built as...it would just have a CE code or something else reflecting the above also stamped on the pad...
