I recently acquired a 1987 1 ton 2wd with a low mileage TBI 454. The computer missing is the only bad part. What I planned on doing was putting a Roller Cam setup in it but herd they had a Vortech supercharger for it. I have a few questions about it. I dont plan on putting the V-Tech SC on it for 6-7 months. But I do want to put a cam, and intake in it before dropping it in the truck. Has anyone had problems with there TBI and a supercharger, or a problem with TBI, Cam, and a supercharger. Is there a particular cam made for this application. Will this cam work without the supercharger on it for a while. Another question is, will the 5.7 computer work with 7.4 motor. The reason I ask is I have a 5.7 computer already. Its going in my 84 1 ton. /forums/images/graemlins/truck.gif It will have a low stall in it. Is that going to cause problems. Opinions and suggestions are very welcome. Thanks for any of the help.
