High Compression BBC for the street

I'm makin this tread because I was looking for input on my ideal BBC build. I'm going to show what I want and try to make a plan for it.

Starting: I have a 2bolt BBC from '75. Has a 9.8 deck height, stock bores, Large oval heads, casting 781.

Now Im lookin for a 'budget' build but this is what I want: 11:1 compression, stock bores, stock stroke, reuse the heads. I'm gonna be running a Tunnel Ram (for looks) dual 650 holleys, and I'll find a nasty cam that will work with the combo. probably 108lsa, 240-250 dur @ .050 and lift around .515 as I want minimal head work. I plan for around 3200 stall and my current combo is a th350 and 4.11's in a 12blt. I'm looin at a 700R4 and 3.9's eventually.

I've been lookin into a 6.385 rod to try and give some extra piston dwell so I can use pump gas but I can't find a Piston/Rod combo to give the compression I want. I've been gettin a lot of Flak for wanting to run 11 or higher on the street. Some say it'll be too "finniky" or "no fun". I beg to differ.

End statement: 400-450hp, 454cu.in. not worried about driveability from this weekend cruise. Oh, It a 69 C10 and will have a 6/6 static drop.

So, suggestions on compression? Rod/Pistons? Cam? Head work? Block Work?
