Which combo to go with
I purchased some new heads and cam for my car and need to know what should be the ideal intake combo for it.
I have vortec heads and TPI base now, so i can't use that, Heres my options.
Option #1.
Canfield 195cc aluminum heads
LT4 hot cam w/1.6 RR's
Edelbrock TPI intake base.
Edelbrock TPI runners (already have)
58mm TB (already have)
#30 injectors
I can reuse alot of stuff with this combo and save alot of money, but i don't know if it will really hurt the potential of the heads and cam.
Option #2
Canfield 195cc aluminum heads
LT4 hot cam w/1.6 RR's
Holley stealth ram
#30 injectors
small cap distributor (will need to get)
This one obviously costs more, but i can sell my old stuff and get alot back. I don't like the idea of loosing so much torque though. And i don't really want to rev it over 6,000 RPM. (I did a search and can't find a solid answer on if it will even fit under a stock GTA hood)
Option #3
Canfield 195cc aluminum heads
LT4 hot cam w/1.6 RR's
RPM intake
Holley 770cfm carb
Performance HEI
I can probaly do this one for what i sell my TPI stuff for, and maybe even pocket alittle money. I like carbs and find them easy to tune, but i like the driveability of fuel injection.
Anybody have any suggestions????

Use the EFI intake manifold that comes on a GM Ramjet 350 crate motor. Fits vortec heads.
Makes 350hp with a tini tiny mild cam, will make tons with a Hot Cam.
Its available as a separate part now. You can use
the GM MPIiv EFI controler, or your TPI computer and wireing ( chip tuning) or a Holley or FAST aftermarket EFI setup to manage the Air- Fuel- Spark .
