Sorry, couldn't go ford always been a chevy man. Seen a 453 in a similar chassis. Google 453 runaway. Would be a tight squeeze. Found specs on Detroit deisel motor. The 471 is actually shorter than the 453 ( 36/39).
Could probably get them in but starting to lean back to upgrading a stovebolt. You think it is worth trying to find a 261. Would it be that big of a performance jump from a solid 235? What are some of the tricks to getting a torquie motor
Also I live in the mountains of NC. Would like to improve engine breaking, that was one reason looking at going deisel.
