Wow man, that really sucks the engine is hydrolocked! You ought to check out the guys/gals at BMC Performance, one of our supporting vendors here on the Z:
http://www.bmcspeedshop.com/
I have not dealt with them myself, but I have heard nothing but great things about them and their reps, some of whom post regularly here, and they offer some of the products you are looking for and so should be very helpful to you in answering your questions and coming up with a solution that fits your truck and what you're looking to do!
You can also check out their contact info here:
