ding ding ding, i think we have a winner

and i agree .030 is a good place to start, if the issue persists, try making the gap a little smaller.

this isn't a metric conversion thread

So is this sound that everyone is talking about like the motor is still running after ignition is shut off? I had a bad centre shaft in my factory 4 barrel carb and it would always idle at 1.5k rpms. When I shut it off it would shut down, then make a noise like the motor was still running for a couple of seconds.

Needless to say I swapped that bitch out for a edelbrock 1400 series.

Right... the poping sound was actually the rebound of the sound off the concrete under the car as the downpipe aimed straight down..

The cars running mint at the moment, 4psi and no vtec... ith the VTEC part, i just tried to make a switch of the 12v to the ecu and to the VTEC wire. It didnt work tho.. would that be because i used 12v goin to the ecu... should i use it somewhere else.. it definatly does something, but just sounds like its sorta missfiring.. i did do it when i was driving the car as well.

Thanks guys! Ill post some pics of the whole conversion soon

Our 400sbc sometimes dieseled for a couple seconds after the ignition was shut off, when it was still running a quadrajet.
