I am hoping somebody can help me with an ongoing problem I am having. I have a 94 fullsize blazer which I put a 383 stroker in which has a 1005 cam
. I have an edelbrock intake and the larger Holley throttlebody. The engine runs real strong except for when I accelerate from a stop or drop the pedal down while on the go, thats when I get a lag before it really kicks in. Sometimes when the motor is still cold, it will stall while stopped. I have been to several shops and I think it has been narrowed down to the Throttle position sensor and/or not enough fuel. I have also been told that the TPS can be adjusted and for the fuel problem I could use an adjustable fuel pressure regulator or I have to put a 4 barrel carb or tuned port injection. I have put too much money into it already and not sure where to go....can get any straight solid answers here. Can anybody help please.
