If I had the money to convert the fuel system in my car I would definitely get the PERFORMER RPM FI kit because you don't need a laptop to reprogram it, and the kit already includes a preprogrammed chip for your engine specifications. This kit also comes with very good intake.

First C3 General Poster!
Im big on trying to bridge the gap between classic styling and performance heritage with modern technology, but I voted for a carbed up system with injection as well.
My C3 will have some technology integrated into it, and the engine, but all that technology is going to enhance the original SBC design and function as intended 33 years ago.

I have the controller for:

And have read up on the others. I like the fact that I have control over everything. With those 'brand-name' ones, there is no flexibility. Bah to that. The other plus is I can make it work with all kinds of different EFI setups.

I have always thought I would love to have the Holley Commander 950 in mine. I love the look of the setup, plus you can keep your original air cleaner and it maintains some similarity to stock look.

NOt that this has much if any bearing on today's situation, BUT, ten years ago it was rather difficult to do a DPFI setup that was not a stock controller, true that T-body systems existed, but an old OLDS racer friend with a '79 442 and a 455+++ turning like 11 seconds, but even he gave up and went back to carbs....shame really, would have bought that setup for the Goat, but it was just T-body, and so not what I wanted....
Not sure what I"d buy today, but cool looking is still a TPI setup, and what for electronics?? I am open to suggestions as mine is a stock setup with aftermarket chip I can't access easily....

I really am looking into TBI. It is a lot cheaper. and I think it would provide what I'm looking for: better mileage, more power, and improved cold starting and throttle response. YOu think?

Edelbrock now makes a new drag racing version of the proflo EFI setup. It's supposed to be good for up to 1500 hp for both sb and bb chevy. Injectors are some kind of variable rate set up, 60-80 lb/hr. rating I think. Don't know the price on it.

I'm putting a modfied LT-1 manifold on top of my 4-bolt 412 SBC. I have the equipment and software to do my own eproms, and I'm ready to get to work. This is gonna be fun...

THe look of a TPI system is unbeatable. If there was a kit that fit under my 75 hood and was programable it would be nice. If rom chips are needed a rom burner and chips with the kit could come in handy.
Although I must admit Im a cheap-*** and if I ever go FI on the C3 I would go mega-squirt.

From the product discription, the new FAST XFI system sure sounds like it does it all. Including built in wideband O2 capability and sequential cylinder injection.
I own a MEFI (GM RamJet 502) and the Holley Commander 950 systems. MEFI is a good system if all you want to do is plug it in and go. It is very difficult and expensive to get any real diagnostic or reprogramable capability.
Like Zwede says, the Holley system is extemley flexable allowing full programability and relativly affordable. I love it, however, it is getting a little behind the technology curve. It still utilizes bank to bank injection and requires external electronics to support wideband O2.
I called FAST and they seem to be pretty proud of there technology.....retail ~$2500 for complete widband system including harness ( not a full system including intake and throttle body like the Holley Commander 950)
I think I will wait a little for the competition to get the price down before I upgrade the MEFI

mrvette,
The big issue with reprogramming the '7730 and similar computers is the funky memcal unit. I'm going to get one and modify it for a replacable chip, but I'm also plenty afraid of destroying a good memcal. There are a lot of people out there who do programming for a fee, if you already know what you want it should help keep the cost down. For more info, check out the gm-ecm section of diy-efi.org. Anything I can help with, feel free to ask.
