So, I blew the stock TBI motor in my blazer finally. I have multiple options for replacement, but the one I'm considering the most is dropping in a near stock 454. I have a decent running carbed 454 in the back of the garage right now, but what would I need to make it work? I'd more than likely bolt on a set of headers, and swap out the cam and intake for something more TBI friendly (edelbrock) but what else do I need to make it work? Basicly, would it be as simple as swapping all of the sensors onto this new motor along with a 454 throttle body? Or would I have to round up a new computer and other related stuff as well? I'll also be ditching the 465/241 with SYE in favour of my 400/205, so would the conversion to electronic speedo be as simple as rounding up a toner ring for the 205?? Thanks for all your help, Chad.
