Lumpy Cam Selection

I would like some input on a camshaft
I have called crane and the fella was more than nice, I am not sure if I was satisfied with his recomendations.
I want a noticeable lump at idle, however I want all my vacum accessorys to work (power disc brakes) I want to use stock diameter valve springs and a stock converter
going into 66 ElCamino 350 cid Edelbrock intake (do not know model) Holly 650 w/vacum secondaries & headers Everything else is bone stock.
Thanks in advance for any input

Go with the cams these guys are suggesting and set the idle speed at about 500 rpms. That's as close as you are going to get to a nice choppy idle without drasticlly affecting your cars performance.
This reminds me of a good friend of mine who was in the right place at the right time when he bought his first car. He bought an early 70's challenger with a 440 that dyno'd 500 HP at the crank for I believe $1500-$2000 about 12 years ago. The car was a little rough, but had a decent paint job. Anyway, this thing was quick, one of the quickest cars around amongst the teenage crowd, but it idled smooth as glass at 900-1000 rpms, so he wound up always driving around with the idle at about 600 rpm just so it would sound tough at idle. This was the last car that needed to sound tough, because it was. He had plenty of power but it was his first car, and it wasn't right to him without the rough idle.
