The p.o. told me it was a 283 and was from the factory. I ran the numbers on the block and they are definately for a 265. I have read in a few different threads that the 265 was never factory installed in a 57 3100. I just got my shop book in the mail and it states that the only V-8 from the factory for the 57 3100 IS the 265. Now I need an answer to know if I should try to get the little 265 running, or pitch it in the corner and go for a somewhat customized drivetrain... Anyone know for sure which engine belongs in this truck? Thanks- Dano

Usually the shop manual is right on, but I had doubt for a minute there.lol I can turn the 265 over by hand, so I might work over the wiring mess and try to get her going... I noticed that I have the oem style front motor mounts, but they are bolted in and not riveted. is there a way to tell if it was done aftermarket? Thanks-Dano
