What is the best idle rpm for a 292?

By Pete 55Tbird - 16 Years Ago

What color is your car?

By 55Birdman - 16 Years Ago

500-700 if color isnt an issue

By cbass139 - 16 Years Ago

it's a blue '58 f100 but not sure what color has to do with it. It does have a two barrel holley and I had it set at around 600-700 rpm and it would stumble and even die at times but at 800-900 it sounds like it is way too high.

IIRC, a 292 with 4 bbl and FOM should idle at 450, per the 1956 car service manual.

Mine has a bigger cam with more overlap, and i can get it to idle around 500 to 550.

Both of those are with the car in gear.

Not sure if its different for later years/trucks. No mention of color dependencies in the manual either!

If its in a red car, it needs to be about a hundred RPMs higher...

My truck is red and white two tone so that makes my idle about 800-900. The cam may be the reason also. Tongue

Two tone does kick it up a bit. Mine seems to like about 750, also a non stock cam.

Thunderboy:

Try shutting your engine off while it is still in gear. That should stop the run-on.

Baby blue is normally at 800 but at 700 really starts shaking he butt.

By gentz - 16 Years Ago

Mine will soon be like tim's at about 800-900 rpm

By mr.uglyduckling - 16 Years Ago

ok what the h e double hocky sticks does color have to do with the idle?

By BFOOTER03 - 16 Years Ago

Color has nothing to with idle speed. Just a little "Y" style humor. BigGrin
