upgrading my 360
Here is a
link to Comp Cams 2012 catalog. I've been spending quite a bit of time on there.
I would verify that you truly have a roller cam LA block by pulling the intake and having a looky see. If you are already running a roller cam, it should look like this.
If the block is a roller but doesn't have a roller cam in it, it will look like this.
Already having a block set up for roller lifters can save you about $400 because you don't have to buy retro-fit lifters. Honestly, if you are just wanting to wake up your 360, a good hydraulic cam and matching springs would do you fine.
