I recently put a 340 intake and thermoquad on my 318. Got it all put together and it wouldn't start. Eventually after some time of cranking I got it to fire momentarily. Ran extremely rough before dying a few seconds later.
I did have to take the distributor out to loosen the intake bolt covered by the throttle bracket, but it is back in the right way (I verified) and I checked the timing while cranking (5˚BTDC)
Carb is full of fuel, accelerator pump is working.
Any ideas?
