I recently built a 306 with srp 10:1 pistons, twisted wedge heads, track heat intake, stage 1 cam, 70 mm TB, 76 mm mas, 30 lb injectors and a 255 lph pump. I also put a new clutch in while i was in the process.

So i get it in the car and start it up but, it wouldnt idle. Soi worked with it and got it to idle so i could set my timing and set my fuel pressure. I set the timing to 16* btdc and set the fuel pressure at 35 psi. Now the car pops alot. it will idle and rev ok but as soon as i try to move the car it starts to pop. I did have it not popping at all but I readjusted rockers. Before i readjusted the rockers it would let me give it gas but, had absolutely no power.

Can anyone PLEASE help me here i have tried everything. I dont have any disconnected vacuum lines. The only thing i can think of is on the bottom of the upper intake it has a connection that has three vacuum tubes coming out. 2 small ones and one big one. I connected the big on to a hose that come off the fire wall from where all the vacuum lines run to. The 2 small ones i couldnt find any vacuum lines for so i capped them.

I really need help.
