best upgrades for an LT1
I have a LT1 out of a 94 camaro. I have headers and exhaust and MSD optispark, relatively stock. What are the best upgrades for an LT1, I am looking to make about 400hp. I was thinking about a cam and injectors but Im not an expert and thought I would ask if there are any better upgrades.

400 at the crank or at the wheels?
400 at the crank is easy: an LT4 hot cam will get you close, or a slightly bigger cam and you are there for sure. If you want 400 at the wheels, you need headwork: either port your heads or get aftermarket ones.

A huge bang for the buck is going to a steeper gear ratio. What do you have now?
Man. or auto?
Man.- I would do 4.10s.
Auto-3.73s + a 2400-2800 stall convertor.
Hotcam w/ 1.6 rr & 3- angle valve job w/ thinner head gasket.

I just installed a Comp Cams XFI 466. This cam has .570 intake/.565 exhaust with 1.6 rockers, 218 intake/224 exhaust duration at .050, and 113 LSA. There are no retainer-to-valve guide or valve-to-piston clearance issues with this cam.
