Here is my set-up and car purpose:

Stock 402 bottom end, with additional unshrouding of exhaust valves on the cylinders. Using Speed Pro TRW-L2242's with a .335 dome for hopefully 9.5/1.

Heads- 820 w/ mild port and bowl work. Considering punching intakes out from 2.065 to 2.19 and leaving the exhaust at 1.72 due to shrouding. Going with undercut performance valves. Harland Sharp roller rockers.

Intake- Performer 2161 large oval port dual plane

Carb- Modified '70 Quadrajet

Headers- 1 3/4 prim./ 2.5 dual exhaust

Tranny- Stock M20 4/sp

Rear- 3.31 12 bolt Posi w/ 14" SS wheels

This car will be primarily cruised and road tripped. It will never see the strip or the other side of 6K for that matter, but I still want it to run. Based on that, I 've chose compenents for a Idle-5K power curve. I've tried to research as much as I could, but still can't seem to decide. Some have suggested a longer duration, but that seems to move the power curve too far up the RPM scale for me (at least I think) and may make it harder to manage at cruise. Others have suggested a longer duration on the exhaust side to compensate for the smaller exhaust valve, and that makes sense. Here is what I've narrowed it down too. Your comments are greatly appreciated.

Thanks for the help!

I'd go with just an old CC 270 Magnum or Isky 270 Mega.. (The Isky will cackle some more than the CC cam b/c of being on 108 centers)...

Nothing fancy at all..

I know there are more powerful cams out there but these should do you nicely, imho..

I'm runnung the lun-60202. My combo is very similar to yours and it's a good cam for what your looking for. It has great throttle responce and runs strong.

I ran the CRN 134242 in my 402 motor with a 10" comverter, it worked well. Either this or the 133942 would work well. THe 134242 has about 12" vac at idle.

Run the Lunati 60202. Your 4-speed and 3.31 will thank you for it. Anything bigger would like over 10:1 and a better manifold/headers. The 60202 is good for over 6000 rpm, peak power about 5200. It has a very good idle sound to it, as well as great throttle response.
You will like it.
