Hello,

I have a couple of questions. First what is the difference between a roller block and a non roller block? Do you have to do anything special to put a roller cam in a sbc 400 block? And what is the difference between a roller cam, and just a solid cam?

Thanks

ONly real difference is that the lifter valley has provisions to bolt down the spider that holds the yolks between the roller lifters to keep them from turning. You can do one of two things here:

Tap the lifter valley making sure not to gouge your cam bearings and secure a spider with some locktite, buy the yolks and do it stock style (it can be done, I've done it myself with a mopar 360).

Or, get an aftermarket setup with the links between the lifters. This setup costs a couple hundred more and some people don't like the idea of a little bar keeping your entire valvetrain tied together.... me either.

You'll want a cam button or an anit-walk bumper or plate or some kind to keep the cam from walking forward.
