Moved to a vette
OK guys I know how to use the search botton and found alot of atricles on the crossfire injection. But i wanted ot be able to get it up there to around 300hp. I saw people said throttle bodies, headers, exhuast, and intake mani. The question is where could I get most o f these items how much would they be and what would actully get my car up to par? I know i dont want to get a carb and heard that the xram isnt worth it, but maybe someone could really show me the way. Im not looking for a speed demon just want my corvette fast than my GLI. I love the vette because it RHD but seems like the engine i have is a bit out of style. Im sorry I had to bring this subject up on this again but seems like I needed a more direct way to figure out how to get this thing working.
Thanks and this forums looks well organized then others.

Get a dremmel, port your intake manifold. That right there is your biggest problem. It will free up a lot of power. Then swap your fuel pump for the '85 style. That way you have the fuel at WOT. The '84 pump is about 13psi and the '85 is around 30psi. I think. It won't make a difference at low throttle because of the pressure regulator. But it helps when you are punching it. Port your head's, and put on a better exhaust. And some 1.6:1 full roller rockers, and you should be doing fine on power
If you can afford it, put on some better heads.

Watch for posts from CFI-EFI on the cross-fire. His runs in the 13s with virtually nothing except intake mods.

Hogwash! Another old wives tale. TEST your fuel pump. If it puts out the regulated pressure at the times of highest demand, WOT, heavy load and high rpms, it is dong it's job. If the pressure doesn't drop, the engine is getting all the fuel it can use (more, really). Once the engine is getting all the fuel it can use, providing more is a waste.

Banned for life Im in va beach do you know where I could get my intake mani ported and how much it would be. Where could I get most of these parts. It seems like most of the parts just have to be ported/ bored out if im right? I already am getting a new exhuast so seems like im on my way. Can I pick up a used fuel pump or should I just get a brand new one.
Thanks for all your help.

When you take your intake off to port it out, you might want to consider a better set of cylinder heads. Aluminum heads are always a good option and you can find good ones just by searching this forum. You can use just about any heads designed for SBC up to '86.
