Stock 360 Upgrades for Crusher Cuda?

I don’t know what the 051 head is, but if it’s an open chamber the piston needs to come out of the deck.
Don’t buy an off the shelf cam.

Your biggest issue will be headers. There ain’t a header worth a single crap out there for that chassis. Not one. I haven’t seen an off the shelf header that wasn’t 40 HP or more off a decent header.
whoa whoa WHOA on the first part I quoted!!!!. LOL :D Pistons do not NEED to come out of the deck nor does one need 10 to 1 compression to run 12.9's in a A-body with a 360. And, a cheapo off the shelf cam will get him his goal also. Your way would optimize the build and isn't wrong, just not necessary to reach his goal.

You are correct on the 2nd part I quoted about the headers. Although, even a bad header will be enough to meet his goals.
