Im trying to get some input on taking out my q-jet and going with EFI but with the vacuum requirements and the cpu and what ever else a totally stock 81 would need. Im just looking for plug and play not trying to gain thousands of hp just better mpgs and all the bennies of EFI, its all stock except for headers dual flow exhaust and intake manifold
there are a lot of different brands out there are there ones to stay away from and is there ones that are bullet proof, or are they just like most things you get what you pay for

I have an 80 vette and am looking into the Fitech Go EFI system. Some good videos on youtube about it. Simple plug in and self learning. There are other systems out there some similar to Fitech and others that look like one heck of an undertaking to me.
I have had my carb rebuilt several times and it's leaking again. Just getting tired of all the issues with it. Todays fuel injection systems are more reliable then ever before, better mpg, and better performance. When you look some of the videos of a first start after an install it's impressive.
Corvettes and women are the same...You want to make love to them but they keep breaking down.
Vette(s): 81 beauty all original (not anymore!!)
Its more fun now!
I used the FAST efi system. Other than putting the pump in the fuel tank it was easy. The only issue was the map sensor. FAST makes a great unit but the one place they cheaped out was using a pos sensor. I got a delco unit at PEP boys and it has been flawless ever since.

I put a FiTech Go Street EFI on the wife's '87 Olds Cutlass 442 last year. The engine is a 350 Olds V8 with a pretty lumpy cam. I'm very happy with the unit. It is very affordable and is self learning. I did have one small glitch, but a couple of simple taps on the touch screen to reset and change the camshaft selection the unit was up and running. I opted to use a in-tank fuel pump with a C5 Corvette filter/regulator to supply the correct pressure. You can do that or they have a Fuel Command Center that takes the fuel from your stock mechanical fuel pump to fill up the sump. Inside the sump is the hi pressure pump and regulator that feeds the EFI unit.
The car starts so much easier, no more choke to worry about and my mileage jumped about 4 mpg's. The more you drive it, the better it gets. It's a fairly simple system to hook up. You are going to have to ditch your computer controlled distributor for a stock non computer HEI or go with a MSD unit.
thanks for the input just looking at the numbers AND idk a G for EFI a G for heads and as long as the heads are off should replace the cam and then pistons crank idk then what ever else what is it going to cost for a sb 350 350hp installed just in parts I think I can do the swap I do own a great set of left handed screw drivers
