Heard back from Patrick Guerra this morning. I'll be sending off a engine specs page to him and will be getting a custom cam done up. With the cam he's spec'ing for me, he figures it should be 525-550 flywheel hp, right where I want to be. That way there's room for head upgrades down the road. The cam will also be a good pro-touring cam. As he put it, it will have good street manners and a wide power band. Once I get the cam specs, I'll be ordering a Speartech ECU. Thanks for all the replies guys.
Oh..if anyone is interested in getting Patrick to do up a custom cam for you, here's his website link:
