A friend of mine built a 383 stroker and we put it in my truck. The 350 has a set of 882 heads and we put the edelbrock stage 2 manifold on it and a adapter plater so that I could run my 670 Holley T.B.I. on it, and when I take off it wants to die if I give it to much gas but once it is going it does great. If I rev the engine to two thousand RPM it sounds fine but below that it is very rough idleing. It has a 2000 rpm stall in it. My question is that I need to know if that the TBI is ok to run on there or do I have to go to a 4 barrel and if so, does it have to be a carburetor or will a 4 barrel TBI work. I really dont want to have to switch it over to carb and take my computer out and add all the extra parts to switch it. But I need to know if I'm throwing money in the wind or can I keep the TBI and computer. Thanks for your time and I am looking forward to some replies. Yall have a great day. The truck is a 94 Gmc sierra it has a JET stage 1 chip on the computer and a MSD performance coil pack. If you need any more information please ask.
I believe that I have to have a custom chip made for it since it is so much of a difference. I am having a hard time finding someone local so I have done some research online and found a few places that do custom chips. I do not think the stage 1 chip is enough either. I thank you so much for you advice.
