Hey guys, newbie here. I have a 23 T-Bucket with a blown small block 350 with dual 4 barrel carbs. In a matter of about 24 hours my idle rpm in park have gone up to 1500. When cold the idle is normal, after she’s warmed up rpms will stay at about 1500 rpm in park. I’ve checked for vacuum...

(390 fe, hei dist with msd 6a, comp cams CCA-CL33-224-3, 7105 edel intake, 670 quick fuel brawler, fmx transmission) I recently put a new quick fuel carburetor on my engine after not being able to fix my off idle hesitation with a street avenger. The carb runs great except for it seems unusually...

What is a good RPM range for a muscle car? A lot of the cams I am seeing have a operating range that start around 2500RPM or higher. That seems really high to me for a street car. Does the operating range of a cam dictate the idle speed of the engine as well? If the operating range of a...

Just bought a 1980 Camaro with a 350 and I am looking to fix her up. Came here because I am having trouble with the car idle in gear. Idles fine in park but as soon as I shift into any gear she bogs down and dies unless I butterfly her for a few moments. I have changed out plugs and wires...

Hey ive been working on trying to figure this weird idle issue out and havent quite cured it...its a 1980 454, edelbrock performer intake and carb, headers to glasspacks... I attached a link to a video of the issue. The idle out of the driver tailpipe is smooth, only has this minor surging out...

Any ideas? I inherited a 2000 Silverado with a vortec 6 litre. Before receiving it, the exhaust was re-done and cats removed. The check engine system was disabled and cannot be read. When the truck is cold and in gear, the idle jumps up and down, and will eventually die. The idle is fine in...

Hey everyone. Ive got a 1980 454 in a 59 chevy truck. The engine began running rough a while back, not too bad, and its slowly gotten worse to the point where its time to get it figured out. I just checked for a bad head gasket with the combustion leak detector and it passes and the plugs...
