Would this truck accomodate a 1951 270 cid GMC inline six engine? Would the motor mounts be the same? would it mate up with the same transmission? | | |

1955 1st GMC Suburban | 1954 GMC 250 trailer puller project | 1954 GMC 250 Hydra-Matic | 1954 Chevy 3100 . 1947 Chevy COE | and more...
It's true. I really don't do anything but browse the Internet looking for trouble... | | |

You may have to change the starter ring gear depending on which combo you use....but not rocket science....just look and measure carefully | | |
