Hello all
Keithb7, it is a long block 25'' but it is a 251 CI.
Dozerman51, thanks! I have a WC-51 (1943) modified in fire truck just after the WWII. I would like to replace the 230 by this engine.
Chrysler41, nice engine, I will keep mine grey too. As Merle and Don explained, it is the location of the oil filter. You can see it on the botton right of my last picture and on the Don picture.
Don, thanks for the sketch. I thought that it was original full flow but in fact you need to plug the pipe, I got it now!
Regards
Michel
