New valves/ valve springs with new cam?

There are a number of things to consider. What do you want just a nice street car?

Most cam upgrades are going to want at a minimum a rear gear change to take advantage of it. I run a Comp HE268H in my 318 (in a 74 Dart Sport). I also swapped out the rear to an 8 3/4 with a suregrip and 3:55's, it runs pretty good with the stock converter and those gears.


First things first, decide what you want. Street car that you can cruise on the highway too?
