- Problem got progressively worse and car won't idle. Smooths out at about 1500 RPMs. Backfire from driver's side more frequent. While underway, car runs just fine.

Setup: 427 side-oiler, Edelbrock Performer RPM heads and intake, Holley carb with vacuum secondaries, MSD ignition, coil and distributor.

Thanks for any help.

Simpler ideas that take 5 minutes to check:

Did the bolts that hold the carb to the intake loosen?
Is there a fuel drip from the carb to the intake (exterior staining)?
Did you have a backfire through the carb that could have blown out the power valve?

Which MSD ignition set up do you have? (be specific)
MSD Box?
MSD Distributor?
MSD Coil?

PS: Backfire on deceleration, if so, tighten your header bolts.
