I recently got offered a TBI motor out of a 91 suburban to go in my 84 Blazer. I've got a built 350 in right now with a Holley 650, bored .060, big cam, header, MSD etc. What all will I need to change. Probably the radiator, to accomodate the oil cooler lines. Can I keep my headers and just put an O2 sensor in them? What about the fuel pump, do I need a special one that puts out so much lbs. or what. And how big a cam can I put in the TBI motor, cause I will go through and freshin it up. Any suggestions and comments would be appreciated. I am running a m465 and 205 transfer case, with corp 14 and 3/4 ton 10 bolt front end, with 4:88 gears. Want to make a good trail rig out of it. Thanks. p.s. The TBI motor is coming with the harness and computer included.
