Pretty much all one piece rear main V8 blocks either have a factory roller cam or can be converted to have a factory style roller cam. TBI engines do not like big cams, so you need to be aware of that. I honestly think you need to do alot more research before you go taking your motor apart. It's gonna take a lot more than 20 minutes to take your intake off, it'll take that long getting the old gasket off. You're gonna have to unhook the battery, drain some coolant out, undo all electrical connections from the distributor, throttle body, and intake, take the upper radiator hose off, pull the distributor, undo the fuel lines from the throttle body, possibly take the throttle body off, possibly remove the MAP, and then unbolt the intake. I'm sure I left a step or 2 out, but that's the basics. You're gonna need a basic set of handtools, timing light, and a torque wrench wouldn't hurt.
So here's my advice:
-do alot of research, I can't even begin to tell you how many automotive magazines and books I have. Probably around 1200 magazines and around 100 books I guess. I've had classes at 2 different schools and I've been around vehicles practically all of my life. I know not everyone has a background like mine, so I suggest alot of research
-mild cam
-headers
-custom chip
I would suggest better heads but your budget doesn't allow it.
