Im about to buy a complete TBI system from an 87 TBI truck with a 350. Are there any problems with the computer or anything putting this into an 83 blazer? I know it will need a different intake if i keep an older engine. But ive heard people say stuff about stand alone computers, this and that....Im just trying to make sure the computer and harness from the 87 will work just fine and not need anything major to make it work. Also, instead of changing Gas tanks, what would be a good fuel pump to run inline with teh fuel lines? How hard is the swap usually? Very hard to tune and get set up?
