I am experiencing a bog/miss at low RPM when my car is in gear. A friend of mine tells me that I should install a spacer between my intake and carb. It is a SBC with a mild cam, I already have a high rise intake on it. Oh, and another issue would be hood clearance if a spacer will solve that issue. The intake and carb are brand new. I am thinking maybe the accelerator pump. Any advise would be appreciated.
High intake with a spacer?

Hey, A carb spacer is not going to stop the bog. What carb are you using. ? Maybe time for a rebuild.

All I can say is I have a highrise intake, with a spacer/adapter, topped off with a drop base 14"X4" air filter. And it all fits under my stock Malibu hood.
Thanks for responding. The carb and intake are brand new and it is a Holley 670 street avenger. The bog happens when I crack the throttle from a stop. I have to baby the pedal and then floor it so that the bog won't happen. Then when I go through the gears, it bogs down at high end. The distributor is MSD and new as well as I just had an MSD ignition box installed.
Brainstorming this problem has consumed all of my cruisining time and it is very annoying considering the amount of money that I have invested in this beauty. I also have a slow drain on my battery that I have been trying to diagnos, could it be possible for these two issues to be related?
:idea: high rise intake + 670 Street Avenger...
Can we get some more specs on your engine :?: camshaft :?: heads :?: compression :?: which intake is it :?:
Could be that your intake and carburetor combination do not match your engine combo :idea:

on the slow drain problem
get a ampmeter hook it between the pos cable and the batt+
start pulling fuses until its gone
then fix the faulty accessory
as far as the bog goes sounds like you have too much carb try and drop the jets a couple numbers

Sounds possibly like a miss matched engine to me. Depending on the rest of your set up. Depending on what high rise you have, might not be right for a 'mild build'. But I'm also thinking the carb is to big. Just my 2 cents.
