Guys need help, I finished all the work and can not get my car to run properly, I got the timming at 10 degreed advance and the rpm around 890 but when I start to go on 1st and 2nd gear and I give it gas, it has a popping coming from the intake and the car doesn't go like it suppose to go. I have to let go the foot a bit them it will get going but like
lacking of power, then I go to 3rd and 4 or 5th gear and it will reach 120 but still lack of power
please help, I already checked my wires and the firing order is 13726548 I also play advancing +12 or +14 but the same thing,
i have long tube headers used with bbk cats, could be the cats are plugged? but will do the popping ? Thanks for any input, i will start to double check the lash on the valve again also compression test and take it from there but if anybody had this problem before please let me know what it was the solution.
