I have a 1990 5.0 with 4.10 gears, aod with shift kit, 70mm TB and spacer, BBK CAI, 73mm maf, electric fan, adjustable fpr, and full exhaust. I have 30# injectors waiting to go in and plans of supercharging it soon. What do you think the best intake manifold would be since i gotta pull it off to get to the injectors anyways? Thanks

 

If it has stock heads a Cobra intake will be all you need.

 

how many lbs of boost you plan to run?? 30lbs inj may not be the best if you wanna run alot of boost.

 

ya, with stock intake heads, and a novi 2000 set at 8-10#'s of boost i was told to go with 42# injectors... May want to rethink the injectors you have so you dont run out of fuel up top!

 

The Holley Systemax Intake will work well for boost. The GT-40 has it's limitations, the more power you have. You can run your 30lb injectors provided you use an FMU(It's what I use and it has worked well for me). Also, make sure you get a 255lph fuel pump.

 

I was thinkin of just going with the typhoon intake and only running 6 pounds of boost. My Daily Driver

 

That setup will work fine too. But remember, once you get into boost, you're going to want more. I made 7psi stock and had to have more.

 

Do you think heads, roller rockers, and the intake would be better than the supercharger?

 

Nope!!!!!!!!! Go boost first. I wish that is what I did. I did the H/C/I route first and was not satisfied. Plus installing the SC is waaaaayyyyy easier.

 

Cool thanks for the info
