Thinking about this Howard’s cam

I’m no expert on anything but I agree 100% with ValiantS that the car will need more converter to see the max gain especially with the bigger camshaft. What is the current camshaft in the car? If I missed it on the post I apologize.

260/264 565/565 solid

Have pretty much decided if I swap cams, I will go to a roller. Don’t want to risk something bigger going flat staying solid.
Maybe this cam…Vert will work with it
