That's a really, really expensive solution ($2K) for a carb thats loading up. For a mild 350, you could go with an Edelbrock 1406 and will basically run out of the box and be very close. IMHO...

Here is a affordable system to check out. I believe one of our member here tried out this system with good success.

I made the switch this summer.

Rather than a whole bunch of explanation take a look at my post here:

http://www.corvetteforum.com/forums/c3-tech-performance/3670852-fitech-go-efi-review.html

Overall I am very happy I made the switch.  Good performance and reasonable price.  My kit cost $1350 including the fuel system.

Thanks great news to hear Kevin. Sounds like it all went together ok for you. Any minor glitches during the install? 

Yeah it is a more money than a carb, but if ones budget allows EFI is hard to beat. 
Can you post pictures sometime? I'd really like to see it.

Really no glitches except a few busted knuckles!!!!!! I let it learn on its own which was really close to optimum but I decided to tweak the WOT AFR ratio. Just move it 1% at a time and run it for a bit. Honestly I may reset and let it go back to the factory defaults. For now i'm just seeing if I can do better, but i don't think it can be done!! The only glitch i have found is I think I am burning more fuel----But really I don't even watch MPG or GPM!!
I just drive it like I stole it!

I will post some pics later.

Kevin, that looks sweet brother! With that air cleaner on there most won't even know a carb no longer lurks under there. Great job! Thumbs Up

Worth the $$ wasn't it? Wink

Is that a Wilwood hydraulic fluid reservoir for a hydraulic clutch I spy there?

Sarge..... Good eye! yup i snuck Wildwood Hydro for the TKO. You are correct, no one knows that im injected with the large KN and cover. thanks it is sweet and i'm kind of proud how the install went. no kidding--bolt her on and wire up. All wires were perfectly labeled so even a plumber like me had no problem. The damn thing tunes itself and really runs like a bat outa hell! The only problem is you have to be careful taking off as it is instant power. I just may have to get used to itWink

FYI the only issue I have run into is the cheap chinese MAP sensor that comes with the kit. Replace with Delco or similar and it will be super stable.

Jeez, you'd think the company would appreciate a little feedback on their products. That bothers me when they "think" their stuff is ok when in fact it was not. Like you said, we all know better. But, now we can advise others of this issue if they use this system. Glad to hear your car is running good. Thumbs Up

Sarge, thought i would give an update as i have been beating it up for a few months now!!!
Im going to knock on wood here.....But it is still performing perfect with no problems. Anyone who wants to do it, I now say go for it but if your using the fast efi and have problems change out the map sensor and it will run great.

That's awesome to hear Kevin! Thumbs Up

I just ordered a EFI unit from FiTech for my wife's newly acquired '87 Olds 442 w/350 Olds "Rocket" engine. I've heared very good review's about this system, so I guess I'll be a guinea pig. The FiTech unit starts at $795. They are doing a $100 rebate until the end of May. I opted for the 600 hp model incase I want to get a little crazy under there. lol.


Thanks for the update!
Sarge
