just got the 72 all buttoned up . however i figured i would see what timing and idle speed you solid roller cam guys are running? im running a 267/272 .710/.710 lift solid roller cam in my 12.5 compression 406 sbc with a t56 behind it. so far ive set it at 950 rpm. it sounds nasty but it almost seems to be not enough idle speed.

 

I have a solid roller cam, but i have never used it.

 

My cam has alittle bit more duration than yours but go with 1100-1200. Better oiling for the lifters and it brings the overlap sound of the cam out.

 

this is around where i was thinking as well.

 

I'm having a similar issue. I'm running .688/.689 and 264/270, 11:1 388ci...

It's not tuned either but it cannot seem to stay idling at 900...honestly I have it around 1200-1500 lol. I'd say 1200 is a fair number to go with.
