I just put together a 302 with a cam, lifters, rockers, rollers, upper and lower cobra intake, alum heads, bbk fuel rails, 19lb injectors, 65 mm throttle body, fuel pressure regulator...ok thats enough for now. The car sounds great, but when I accelerate, the car misfires..I have been told that there isnt enough fuel getting to the motor. I have 24 lb injectors waiting to be installed, but the problem is, I have looked everywhere for a reputable shop to do the installation, as well as tune it..someone please point me in the right direction.

+1 check fuel pressure. Also, what pump are you running? Hopefully not the stock one [Smile]

24lb fuel injectors would be better on that combo. You will need a matching MAF.

Also, consider upgrading your ignition system.

what plugs and what are they gapped at?

The adjuster is set at stock, which is about 40 psi I think...I had the 24lb injectors in first, but the car wouldnt start so i put the 19s back in...it is the stock pump for now and an upgraded mass air meter. Honestly, I haven't been able to find a good shop since I moved to Fairfield, So I am really tempted to sell it and cut my losses!

Check the pin connectors for the FI harness. Sounds like they are either VERY dirty or not fully connected/seated. A car will start with nearly any fuel injector in it; injectors aren't the issue....wiring is.

I just got a fuel pressure gauge installed and increased it to 45psi..the car runs alot better, but it still needs work. Thanks for the advice, I will try and drop by the shop when I have time..
