A bit of an aussie post but I have managed to grab a Rebuilt 361 big block out of a 760. It runs really well. What are the odds that it would fit into a 114, the engine bays are the same, but not sure if the chassis rails match..

Thoughts

 

Pretty sure they were all built on the same frame..... just springs/axles changed. Don't know if the bellhousing bolt pattern will be different though..... been a while since a played with the older motors.

Yeah cool thanks, I know the bell housing ia the. Same, just not sure on the angle of the engine mounts based the bigger trucks had a bigger, straight chassis amd the 114 front tapers down

 

Ooo, that might be a problem...... Can you find manuals for your truck? And some of the 'larger' models??
