I am starting to think.........
Was blasting along today in my BM, thinking about worn carbs, having to call in Lars etc.........and suddenly the dark side took over and my resistance to fuel injection ( when rebuilding my C3 engine ) seemed to fade away !!
OK, give me reasons for and against please - money is not that important - just want it to run right - everytime.

Pros:
Smooth running.
Better fuel economy.
Look s good.
Tuning via laptop.
Cons:
Expensive.
Additional wiring.
More difficult to troubleshoot problems.
Probably requires new fuel lines.
If money isn't an issue, you want a good looking and good running system, and you're not concerned about originality, I'd say go for it!

Best Upgrade So Far
I installed a Holley CMD950.
It is great!
Starts everytime hot or cold.
Adjust for emission check
Adjust back to perfomance tune
It does take a few hours of effort to get it dialed in.
Wideband O2 helps!

The opposite is true. I have to strongly agree with SanDiegoPaul If you are computer savey enough to operate your home PC and have the smarts to work on a carb, FI should be a breeze.

How does the computer do its stuff ??
On my BM there is a flywheel sensor ( actually 2 ) to give TDC etc, does a Vette system have the same ??
How much difficult wiring - rather than a power wire or two ??
What tuning problems ??
Am coming to Florida in a few weeks time and could hide stuff in my suitcase for the return journey - so need to sort this out kinda quick .
At the moment I ahve bought everything apart from ther carb for a traditional set up.
Although its not the right subject here - has anyone thoughts or experience of which are the beat ally heads and intake to go obn a raodgoing Ford 302 ??
Got more than one project to get sorted.

The Commander 950 (as the poster above stated) is pretty foolproof. I would recommend a wideband 02 also and you will need a EFI throttle body and a new pump/fuel lines. Some on this forum have converted to the GM TPI setup. Lots of info on that.
Do you live outside the US? I am assuming that is why you want to get this stuff while you are here. Also, just out of curiosity, what is a BM?

Yeah but I can see where he is going, little electronic parts (i.e. chips, resistors, sensors, capacitors etc.) can take a crap on you. And without a computer to plug into the car to generate a code you're SOL. Even with, it just makes the puzzle more complex. But granted, a FI vehicle with no electronic problems is optimal.

Hensen,
Remember Renault 30's? For my sins I had one of those ill handling, ugly POS and it was fitted with a carb. A visit to the breakers got me the parts to convert to FI & the difference was unbelievable. Easy starting & better economy were side issues - the increase in power was phenominal, it really felt alive with great throttle response & ran much smoother. The only downside was the insurance company increasing premiums due to it. If I had the cash (& I'd done everything else - heads, smart struts, paintjob, steeroids, etc, etc, etc) I'd have no hesitation in fitting FI to the Vette. I can't see the problem with new-fangled, rinky dinky technology... afterall, the V8 was once new technology

Thanks everyone- would be handy to pick up everything in Florida in one go. Will be there for 3 weeks, so not impossible.
Re question - BM is short for BMW - quite a popular car...........
Having said that its raining here in West Wales and in the next hour or so I have to move (not very far, thank God ) my open 1934 Wolseley.
Back to C3, if I go TPI its gonna bugger up a procharger step later on.........
