car stalls on hard accel

my 2 bbl 318 is doing that now that I put on my headers and dual exhaust. Does the factory '68 2bbl have the capability of adjusting the accelerator pump? I just need to put my 360 in there! Still need a carb, distributor, radiator, fuel pump... every time I add it up seems like I'm still thousands of dollars away :( At least the exhaust is done now!

Been yrs. since I worked on a 318 2 bbl but I don't think they had much of an adjustment. Probably running lean now that you've freed up the exhaust. Bigger jets should cure that but they may be hard to find. I've drilled them out in the past. Make sure and de-burr them and put a little chamfer on them if you go that route.
