This question is primarily for you motor heads out there and anyone else who has knowledge on the subject. Here is my dilema. In the near future I am going to need my engine rebuilt or replaced. My thoughts are that I will replace my current stocker 210 HP with a higher (much higher) performing GM crate motor. Hopefully the 383 HT when it is suppose to debut in July. If it never comes out then the 350/330 HP will do. In either case I will need to get a new intake manifold to accomodate the TBI or if I plan on getting a different fuel injection system (perhaps edelbrocks MPFI). We've all been down the road of the emissions issues. I'm not concerned about passing a visual but am with the sniff test. I will need to get a different computer chip to get my fuel curve where it needs to be but who can I go for that? Is anyone out there that has a similar set up or that has done the homework on this or am I on my own to do my own homework? I'm hoping I can get this question answered without wasting too much $$$. I know some of you have put on TPI systems. Anyone out there running a high performance GM or other crate motor with your TBI? If so...how is it working for you? Sorry for the long post. 1990 GMC Jimmy 350/TH700R4/NP241/10 bolts, 4" skyjacker lift, 35x12.50R15 BFG All Terrains on 15x10 AR Baja's, Flowmasters.
