I have a dilemma now. If I have finished the suspension of my '67, I want to take care of the little powerplant inside. I want to have +/- 400hp/tq @the wheels.
I was thinking about building a 383ci or 355 forced induction. But my biggest problem is that I live in the Netherlands with gas prizes of $4+ per gallon...... so now I am thinking of building a fuel injected engine. I know I'll get more hp and fuel economy out of this, but what is the real difference in hp/tq and economy?
I would check DD2000, but I'm still in this ice cold Sweden....so no DD2000 here http://www.camaros.net/forum/frown.gif

Thanks

I think that the end result will depend on what you build and how you build it. Not very helpful but true.

The fuel injection engine in my '67 makes (on paper) the same HP and TQ as the carbureted version but in racing (APBA) the sanctioning body penalizes the injected version with a 5% weight penalty over the carb version. The EFI motor is more efficient (in general) and does not require constant tuning (once it is set up) and can make as much power (if not more) than a carb motor, provided you are building a "with a purpose".

In terms of economy, that to is relative. I get just under 5 mpg "cruising" and under 1 mpg to the floor. Then again, I don't have to stay to the floor for long...

You won't see a significant difference in power / torque. However, you will gain control over the fuel delivery which will improve throttle response. You know all those guys with off-idle issues? Easy fix with EFI since it's just a matter of tweaking the curve. Also, if you have a high compression motor, EFI will give you a better chance of avoiding lean-out and detonation. EFI allows some improvements in the intake manifold design that enhance low speed torque. Big throttle bodies on EFI systems translate into upper RPM improvements, without the problems seen when putting too big a carb on too small a motor. If your compression ratio isn't too radical, you can gain economy by cruising lean, and still retaining good WOT performance.

Aside from these benefits (which are worthwhile) a well tuned carberated system will run just about as well as a properly tuned EFI system. I tend to like the thought of EFI since I'm a gadget freak. However, the cost has kept me carberated.
