Thanks. Mine has LB manifolds so I'd be getting bung welded on down pipe.

re: Will a regular drop base air cleaner work without the return line connected?

I've confirmed a 1978 W72 drop base will fit without return line. Not sure about other years, but I assume 77-79 trumpet or W72 would work. I removed the vacuum hoses from the base though.

re: mechanical temp gauge at intake crossover

I had an electrical AutoMeter in my crossover. I now rely on the temperature reading from the FiTech display. I may hook my AutoMeter into the head but I don't need 2 temperature gauges so I may just take it out.

re: O2 sender bung

I had stainless steel bungs welded onto both down pipes, had it done by the local muffler shop. I have Pypes stainless steel down pipes so I had stainless steel bungs welded on, AEM 30-4008. I also got AEM bung plugs 35-4001. The plugs seal similar to how AN fittings seal, I just added a dab of copper anti-seize to the threads and snugged them up. I now have an AEM Air Fuel ratio gauge 30-4110. AEM gauge is using one bung and the FiTech in the other. There is plenty of length in both cables that I could switch them from side to side to confirm readings.

Joel Koontz, when I mentioned I had the AEM gauge installed to Ken at FiTech, he mentioned that they will be switching to the Bosch 4.9 senders in the future. I wasn't going to wait for the change. Bosch 4.9 sensors are relatively new, major manufacturers started using them as early as 2007.

You cannot simply switch out a 4.2 with a 4.9 sensor, the hardware side also needs to change in order to read it.

grivera, re: bung hole size

I would not bother using the strap, not even temporarily. Call around, a reputable muffler shop should be able to drill and weld the bungs on in only a few minutes, it shouldn't cost that much. Otherwise, I would make the hole the same size as needed for welding them on, as you will eventually want them welded. If you're never getting them welded, you could make the hole as big as you wanted, so as long as the straps make a seal you're good to go.

I have mine in hand. They weren't technically back ordered, but they ship out as they are built and tested. They charge a $50.00 hold per product (efi and fuel system) then invoice you for the remaining when it's ready to ship. I had mine in hand 10 days from purchase.

In regards to the o2 sensor bung, I'm going to give it a try with the clamps and see how it seals. I'll be changing over my entire exhaust system shortly, so I just need it to hold temporarily. I'll report how well it seals.

That's actually the last piece I have to install at this time. I've got long tube headers and the collectors are situated at a point that I can't get a drill on them at the required 10 degrees or more above the horizontal axis. I'm going to have to drop the exhaust just after the collector and install the bung there.

Thanks Angelo. I should have mentioned my air cleaner is a standard aftermarket 14" chrome drop base. Not sure if that makes a difference?

[angelo]

Do you have a picture of it or a part number?

I just test fit a K&N drop base with 1.25" drop, it just fits and is what I am going to use for an experimental drop base I'm making. I am using a 16" pizza pan with 1.5" deep sides with the drop base. That should get my height back, as the factory base has a 1.75" drop and 2.5" high sides. My current throttle body sits 3/4" higher than the Quadrajet did.

Mine is this one I believe: http://www.carid.com/edelbrock/pro-f...FUgWHwod-ZcA5Q

[angelo]

Looks like the k&n I got. How much drop is it? It will work but the pressed end will be where your fuel line elbow is.

[grivera]

I'll have to measure when I get home. Also, just noticed I linked to a 10", mine is 14".

By pressed end do you mean ends with squarish impressions?

[angelo]

Right. I got the 85-3549 model, it has a 1.25" drop, but when I measured the drop is actually 1.125". http://www.jegs.com/i/K%26amp%3BN/599/85-3549/10002/-1

BTW I compared it to the Jegs house brand (http://www.jegs.com/i/JEGS+Performan...50037/10002/-1), from 10 feet they are identical, but up close the Jegs one is made in China, uses slightly thinner steel, the carb mount area is not rolled and the bends, particularly going into the carb/throttle body, are not as rounded (sharper angles) than the K&N. The K&N has a nice roll to sit on the carb/throttle body and is made in Japan. The Jegs drop is actually 1.32".

I paid the extra $7 for the quality drop base.

From pictures, the Edelbrock looks identical to the K&N with respect to the softer rolls and the rolled metal where it sits on the carb/throttle body.

This is "sounding" good, has anyone done any dyno time with this system? Can/has anyone you run E85 with this system?

[frbformula]

There is a thread in the boost section with dyno results. I just ordered the go efi 8 system and am going to run it with e85.

[salesguy01]

I'm about to pull the trigger on this! my Jet Performance Level 1 Carb is junk on my fresh Butler configured 467 alum head. I already have the TANKS inc. Fuel system in the shed.

Should I go for it?

[JLMounce]

The unit is solid and Jen Bryce and Caren run a very tight ship. They are without a doubt one of the best groups of people and best companies I've ever dealt with.

One thing I would caution is to make sure everything else on your car is up to par. The installation on my end pointed out a lot of things on my car that were in need of some work. The ecu in the unit needs good wiring a clean tach signal and an ignition system that is running at 100%. If you can check all those boxes, I'd jump on it in a heart beat. If not, check those boxes and then purchase the FiTech!

[angelo]

Good advice! I came from a just recently upgraded ignition system which may explain why the FiTech upgrade was so easy for me.

Mine fired right up after I fixed the previous owners tach wiring issues. Then my Unilite distributor gave up the ghost 5 minutes in to first run.

I was ready to drop 600 on a pro billet distributor, 6AL and coil, but Ken talked me in to just going to a HEI and saving the money, since I don't need to retard timing for boost or nitrous use. He sent me out anew dizzy the same day we talked.

[FrankieT/A]

Will the FITech system share the tach signal with the tach?

[angelo]

Yes it shares the signal. It shouldn't be an issue unless your using an old points distributer I believe. Hopefully someone else can explain that.

I will be ordering my fitech next week for my 78 TA. I was pretty happy with my qjet but after seeing the fitech system on my buddies chevelle I was totally impressed. I have always steered clear of EFI because i thought it was to complex. This system has changed my mind. My qjet does a great job but it cant self tune and maximize performance and efficiency unless I make the changes to it periodically. Changes in temp, humidity, altitude, etc all get removed from the equation with a constantly learning efi.
