I have a 91 Gt with trickflow twistwedge heads,f303,msd 6al and distributor, holley 650 dp,and a aeromotive universal bypass regulator monitoring the stock electric fuel pump. My problem is the car wont start, it back fires through the carb or just cranks over. I have adjusted the timing from dead on to15 degrees, also 180 to 360 out and it still won't start .I do have spark and it is getting fuel. Is there something I may have over looked? Any help would greatly be appreciated.
Thanks
