I have been trying to make absolute sure my jeep I bought is a 232 and not a 258. Most info I've found says they came that year with the 232 as a 6cyl but I don't know if it's been swapped out in the last 35 years can anyone help me figure this out since they use the same heads and manifolds.
I can't find the info I need on jeeptech.com, or googling it. I thumbed thru my haynes, my FSM, everything. I was operating under the thought it was a 232 just because of some bad info I got but I theres so much aftermarket stuff and no serial #'s I can find. I believe the transmision is a 150 but I'm not sure. And a dana 20. help a nubee out!!!!
The engine code is stamped on a pad on the right side of the block, just ahead of the distributor. It beaks down like this:
A- 258 1 bbl (71-79)
B- 258 1 bbl Low Compression (71-74, Jeep ONLY)
C- 258 2 bbl (4.2L, 76-89)
E- 232 1 bbl (70-79)
F- 232 1 bbl Low Compression (71-74, Jeep ONLY)
G- 232 2 bbl (70-74)
L- 232 1 or 2 bbl (68-69)
1. Year built code 2 & 3. Number of the month 4. Engine size/type code 5 & 6. Day built
Just an FYI, your gas filter is in upside down, this can make for long cold starts. The return line should be up top so vapor can blow back to the tank on a hot shut down. If it is at the bottom it can drain all the lines when it sits, vapor locking it.
