    i have a 1973 ford Ln600 dump truck with [what i believe is] a 330 or 340 small block original hd truck motor. [ i will edit the post when i look at the truck for the correct size motor] it has the 5 speed with 1st being the granny gear, and a 2 speed rear end. what motors are interchangeable with this truck and trans, the motor is blown, someone told me that you HAVE to replace it with a hd truck motor, the original size if possible. my question is why [as long as the trans bolts up to it] couldn't i put a 360 or 390 big block light truck motor in it, or if a big block will not bolt up, then a 351 ford? i found a used [ millage unknown] original replacement motor for it for $1200. now i know i can get a 351, 360, 390 for at or under $500, but i was told you cant put a car/ light truck motor in it, any advice would be greatly appreciated, any suggestions? thank you for your time, i will post the correct motor later on today, thanks

    If it did bolt up, which I would say would be slim to no chance, the industrial gas engines are made for that application. They are commercial grade motors. You could probably make a 10 foot minute mount bolt on a toyota but it just wasnt made for it. (That was just an example not a crack at toyotas.) I am not tryin to be a wise a** just sayin you would be much better off with replacing what you have.

    thanks for the info, i was using a car motor as example of motors classified with trucks/cars. i would look for a 360 or 390 big block out of at least a 3/4 to 1 ton truck, but i do understand that it will not be as strong but with going to a heavy duty pickup truck motor it should be in the middle of the motor i have now, and a car motor, thanks again for your time and info
