That engine FRESH / NEW should have 150 LBS. compression per cylinder. If you have more then 20 LBS. difference in any cylinder then it is not in good shape and a good VALVE JOB is probley in the furture.
its a chevy, so its too much for your mom and her
can a chevy truck with a 350 engine with a tbi cause detonation and pre- ignition?
YES, That would be a direct bolt in with NO problems. EVEN SWAP
350 tbi
YES, they are both TBI. You will need to keep everything else with the original truck due to computer issues.

It will be a 305 or a 350 fuel enjection engine ( TBI )
Yes.
check the vacume line behind the tbi that runs to the map sensor
170hp@4400rpm 255ft/lb@2400rpm Compression ratio 9.3:1
get rid of the TBI or go with an aftermarket throttle body,Headers,hi perf ignition
It could, but why would you want to? From 87 onwards, Chevrolet went to Throttle Body Injection (TBI), which was a far superior system to carburetion. IMO, you'd be better off to drop in a TBI big block (the 400 was a small block, and ceased production in 1980, long before TBI became a thing).
