rough idel

[snake]

Hey guys what causes rough idel in a camshaft is it lift,or duration.I would like to pic a cam for my 318 with a bit of a rough idel and some more lift with out having to change my push rods and going to adjustable rockers,so i would like to use stock valve train.Its a 318 with headers, single plane intake 3000 stall with 355 gears ,stock compression.Any tips.:grin:

I have a 318 in my '74. I ended up going with the Comp Thumpr series. I has a pretty choppy idle and it still does well with power brakes and A/C. Overall it sounds awesome!

Was it a stright slide in,did you have change your lifters and rockers.

A lot of overlap (short lobe center) is a big contributor to the rough idle, but that together with a low CR engine you won't like the result.
