I picked up a good deal on a 454 from an 85 k30 so it's carb'd. I don't plan on modding the motor, just run as is. I would like to use the TBI from my 350 in the 89. Here's some of what i know (or at least think I know) and some questions I have: I would need big block injectors. Will the distributor from the TBI350 work? (I was thinking I had read a 454 & 350 use the same.) Would it be better to find a 454 TBI intake or can I get away with an adapter for the carb intake? I assume I need a chip for the ECM. In the little bit of research I've done it seems the 454TBI used the 7747 computer but because my 350TBI is in a 1ton it uses the 8747 computer. Can I get a chip for the 8747 that will work with a 454? Just contact a place that burns custom chips? Any other thoughts? Thanks in advance for any help.
