I cant decide ill have the bottem end assebled this friday. Should i stay TBI or save and do a miniram III setup??

 

Your stock TBI needs to be replaced if your putting in a 383, it's WAY too small, unless you want to go with a carb you only have 3 choices, bigger 2" bore TBI, 4 bbl TBI setup, or a MPFI setup. I'm building a 383 too for my 92RS and I'm going with a Holley 4bbl 700 cfm TBI Commander 950 system that I picked up new in the box last year for $800 from someone that needed the money.
