Default Building a beast...doing a 391

A few months ago I had a head gasket fail on my 91 Steel Blue that I bought end of last year update: turns out it was way worse.
At some point in its life a hose clamp had been dropped in the intake.
It apparently sat there for years and then one day, the wife says she hasn't ridden in my new Corvette. So I back it out of the garage (starts fine), she gets in and shuts the door and it suddenly stumbles and start running really rough (not that I'm saying this is all her fault ).
So instead of just replacing the head gaskets, I decided I might as well have a 391 build with cams done by Pete.

I know, how the heck do I go from needing a head gasket to building a 391?!?! Well, it all starts with the little statement of "while you're in there...". I'd already been planning to have the top end ported, but since the heads were going to come of for gaskets, that turned into let's port those too. Which was quickly followed by: it's not that much more to build a 391. Which of course was followed by, let's talk about cams since the motor is already going to be out.

Pete will also be doing a little other work for me at the same time:
installing OBX long tubes, DRM coilovers and a few other little odds and ends. Should make for an absolute beast of a car once it's done!
