To EFI Or Not To EFI That Is The Question

Anyone out there have any experience on converting a carburated C3 with an after market multiport EFI system such as Edelbrock or Holley? What are the advantages? Is there increase in power? Is it worth the buck?

Do you want to spend that kind of money? Holley has a TBI system that will bolt right onto your intake for less than half the cost of a TPI system. In fact Corvette Fever did a show and tell on this conversion, off hand I do not remember which issue. If I find it I'll let you know.

Fuel injection is well worth the money. My 83 pickup jumped 4 mpg going carbureted to Tuned-Port and the power difference is amazing. They start better in cold weather. If you shop around you can do a good TPI conversion for around $1000. $400 harness, $100 PROM, $100 fuel pump, $400 TPI unit, $20 ECM, $30 hoses and clamps. That would be with a new harness, if you are willing to cut up an F-body harness you could do it cheaper. If you have a relatively stock engine in my opinion stock TPI is the way to go.

Yes, I would like to read it Thanks.

IMO all cars should have EFI's I have Edelbrocks Multi Point EFI bolted on my 454 BB and there's no way I would go back to tuning carbs EVER again!

Tell me more! More HP? How can that be unless your carb system was not working properly. They all deliver fuel. Delivering the proper amount at the right time == HP.
So tell me more, I am very interested in doing the swap also. And the CF article stated that, the carb put out more HP. If you noticed, CF did not use a stock engine, why not?

I will be putting an Edelbrock 3550 EFI on my 454. Actually it should have been on it a year ago but I can not get the block back from the guy who has it. I would certainly expect a 3 to 4 mpg increase and definate improvement in reliability over a carb. especially in cold weather.
