Something for you/us carb guys!


and another!

Go EFI 2 Barrel 400HP – Classic Carburetor Gold – FiTech Fuel Injection

A bit pricey I think.

I just finished tuning a Fitech system on a mates 542 big block mopar , it is the meanstreet 800 hp system and fuel command center .
After a few minor problems with the car itself and some minor tweaking , its a beast .
Starts within 2 seconds of cranking , idles nice from dead cold , throttle response is awesome , unlike most carbed big blocks i've seen you can put it in drive and just use it straight away from cold instead of having to sit there for 5 minutes getting some heat into it just so it will idle .
I was a bit sceptical at first , now i think they are a good thing .
Sure they wont do everything that a stand alone system will do , but they work really well .
A far better proposition than screwing around with carbs , a bit more expensive but it will work so much better

yeah looking at carb prices its not a bad deal for all the pluses you get. There a sinch to install and tune.

bigblock Mopar what motor GEN3 or RB(440) based. I got a 440 in my International Scout. Two 6.4L Hemis and a few 318's to fool with.

I really would think about a Fitech on my Scout I run 50/50 E85 on a carb.

This one i done is a 440 stroked to 542 .
Has edelbrock performer heads , roughly 11:1 compression and has a street/strip cam .
Was a real pig to start from cold and even once warm was a bit of a pig , now it runs sweet .
the owner rang me and said its actually scary how quickly it gets into it now compared to the carb which was a 850 cfm demon .
I just want to drive it and do some data logging to make sure the mixtures stay on the targets i set it to aim at .
Found it ran best with the target afrs slightly rich at idle and cruise .
I have it set at 14.1 at idle and low speed cruise , progressing to 13.5 through the mid range and 12.5 at wot.
Could be a touch richer in the top end since it detonates a touch above 5500 , either that or pull a few degrees out of the timing .
Once the owner has a few more miles on it , i'm going to turn off the closed loop so if the O2 fails it wont do anything stupid like go lean and shag a 30k engine .
The seat of the pants dyno feels like it is some where in the mid 500 hp range atw ,this thing really boogies ! Can keep the tyres frying in 3rd gear in the tf727 .

It's really hard to argue with FI. With the new self-learning FI systems, you really have to want a carb to have one.

Any word on what it takes to bolt one of these to an A20?

Its the standard Holley profile so I would guess an adapter to the Honda plate would do. There two or three on here that have done something similar. I don't think its something you could just buy off the shelf.

price may seem high, but i think that is where most lower end systems price point is. IIRC ive seen stuff ranging from $800 to well over 3K for a system.

I will admit even tho i do like the carb on my oldsmobile, I will be switching that over to the efi system when I am done rebuilding my 350 SBO

Now if i did own a carb'd accord, this would be of interest. wonder how well these systems can cope with boost.

My good Ford buddy runs Fitech on a 302 with 10 lbs boost on a cheap turbo setup. He had it dyno tuned and it runs great. The idle comp seems to be the only thing that needs manually adjusting.

They do seem to be a pretty good thing .
Once the idle is set to the correct iacv count , they start beautifully hot or cold .
The only misleading bit about them is how they are meant to be pretty much plug and play .
There is still a bit of setting up to do in the system, nothing major , but you still need to have a bit of knowledge about afr, accel enrichment rates etc .
If i were building a v8 toy , i'd go with a fitech set up

As with any new system there will be a learning curve, all depends how steep.
I have heard about many of these systems being very plug and play, most likely on the very popular stuff. However I've also seen mentioning it would take a typical shade-tree mechanic about a good weekend to complete the conversion. I think these FI retrofits are a better implementation of the electronic carb control and TBI injection days.
Good to hear they can accept boost. I was toying with the idea with boosting the SBO 350, lately i wanted to make a 383 but finding a good olds 330 crank is hard to find these days.

For me it was cheaper to buy a fuel injected car. The carb to efi tech is a really cool I see but people will have to spend money. Cheaper to buy a Webber

Man this thing looks like a screaming deal. You guys are lucky you have a car that came factory with carb and EFI in sufficient quantities, which is why this looks expensive. For any other car, this is a deal as you don't have to fabricate anything. I might even consider trying this out on my 1st gen. This is far less work than converting a DX over to an LX-i anyways.
