Been awhile since I modified one of these cars a few questions

I'm going to start with a few minor tweeks and go from there it's been years since I worked one one of these things

a friend aquired a free 1990 auto that we are going to fix up and have some fun with it will be a budget build but we want to get some extra go out of it

Going to port the 90 blower/plenum/intake manifold
A/c delete
Remove the converters and redo the exhaust
Shift kit
4:10 gear because it's laying around
Fmic with a raised top

What would be a good injector/throttle body/mass air combo?
75mm with a 76mm c&l? Would I need 42lb injectors or would 36 work?

With a combo like that anyone care to guess what kind of hp/tq it would produce?
 
Personally I wouldn't spend a lot of time on the early model blower.

For about $250-300 you can go to the late model and with the proper porting your probably only going to spend $10.00 per HP

Under drive pulleys are a good upgrade at about $15.00 per HP (again used)

I like the AC and other than weight doesn't change WO performance dramatically.

I wouldn't recommend more that 10% OD and a Ken Wagner Dbl Intercooler would probably work fine.

75/76mm with 42's and a tune should get you close to 235-240 rwhp.
