340 cam advice

If you are OK with an aggressive idle, look at the 60404 voodoo cam. It's another that will make pretty good power if the heads are decent. The XE275HL is a good stick as well. Lots of cams can work with what you want to do.

A good converter is an area to spend $'s. Get a good 9.5" unit that flashes hard and still drives like a stocker at part throttle, you will enjoy driving your vehicle a bunch more.

There are plenty of people that have and do make camshafts that some in here think are too big to work, pick what you want to do and run with it. A lot of it is in the tune up. 3.9+ gears are not part of that program either!
