I'd say if this motor is in good shape,good compression, not smoking, using oil or making weird noise, run it. But, I'd be looking for a 261 to replace it with when she is worn out. I'm running the same motor in my old coupe now has post 54 crank for full pressure oiling etc. But the snag with these older 235s is the head, very low compression and you can't just mill the thing.
Best of luck and very cool truck BTW.
