I have a 54 F100 that has been outfitted with IFS so none of the original motor mounts or crossmembers exist. I plan to put a 292 back in and figured it made sense to put it in the same place the original engine was. I was hoping you guys could help with some dimensions. I plan to center the engine left-right but need help with the front-back and the up-down measurements. Any help would be great. Thanks.
