84*86 truck 318

Use your best judgement.
I bought a 440 once out of a motor pile at the local junk yard for $40.00 complete with carb.
It would not turn over, I seen the problem a converter bolt lodged in the flex plate and block.
Turned the motor back bolt dropped out, it has been running in my cousins 69 charger for about 10 years now with only a couple of gaskets changed.
