Re: Favorable Crossfire Thread
Pretty easy really. It is a U-shaped piece of clear tube, you can use vyhnal tubing and a board. I used some clamps to hold it to the board. You stand it straight up and down and fill the tube 1/2 way full of water. Then connect each side to your hoses. Once you get the tube back level, you are balanced.

Re: Favorable Crossfire Thread
Just traded a vehicle for a 1983 TA with CFI. It was running rather well but is going to require a new engine unless I devote an entire rebuild bottom to top(really not worth salvaging the 305 at this time), my mechanic is in the process of price checking on a good 350, and everything synced up. I will probably keep the 305 if there is no core fee for a later rebuild on a different vehicle.
The shop suggests putting MS on it before buttoning it back together to optimize performance and weed out hiccups. I am curious on what experience people have had and benefits to fine tune the CFI system? I am familiar with computers and programming so it doesn't intimidate. From what I have been researching it seems like a good bet.
Goal. This is going to be a regular driver and long term 'tinker-project'. Not looking for beast power or race stock or going back to complete bare OEM. Thank you!

Re: Favorable Crossfire Thread
I know that no one has posted on this thread for a while but, got a question. My Camaro still has the 305 under the CFI. I got my Renegade Intake Manifold (looks beautiful lol), putting in an electric fuel pump, rebuilding the TBI's, going to change all the sensors, replace all the vacuum lines, dual electric fan, getting rid of the cats, and setting the fuel pressure up. Is there anything else that I could do to get a little more power? I was thinking TBI spacers because I found some for cheap, even though a lot of people think that they don't work, but, not sure if it would cause problems with clearance.

Re: Favorable Crossfire Thread
If I recall the Renegade is a large runner manifold. It may be too large for a 305. But give it a try. As far as clearance it may be OK. I would measure clearance to hood or top of AC assembly.
Cranking up FP presents its own issues. Crank, choke, AE, open loop will all be proportionately richer and fuel mileage will suffer as well as drivability. Cold manifold upping FP will help in drivability but once it goes CL it will be too rich. Up FP is a crutch for getting PE correct and that will work for PE A/F.
Best idea is to learn DIY Prom on that Forum.
I did what you are referring to many years back. It did not turn out well initially. Today I have port fuel on my CF and it was the BEST idea/result for my current set up.

Don't forget the exhaust manifolds. Replace the factory 2" units with L69/TPI 2.25".
The spacers may add a tiny bit of throttle response and power.

Re: Favorable Crossfire Thread
Ronny, luckily I have someone that's very knowledgeable about vehicles, except the CFI, that is helping me. I'll admit, I don't know much about vehicles so, while he's helping me, he's going to teach me. I would jump head first into it but, have read these systems are VERY touchy. I'm going to let him read your post in hopes we don't run into any headaches. Chazman, the car now has Hedman headers and a Flowmaster exhaust from the previous owner. Once the guy and I start on it, I'm going to have him look everything over to make sure everything is in order. KITT1983, I'd like to know as well what you think about the Renegade. Is there anything else that him and I could run into? Any help would be appreciated. Don't want to be a way from my car for to long.....hahaha

I've had the Renegade on my car for 2 years, need to get it dyno'd so I can measure HP difference.

Re: Favorable Crossfire Thread
Need to get extra thick valve cover gaskets or shave the underneath off of the ones I'm putting on and make a gasket for the top plate. TBI's have been rebuilt, all new sensors going in, new vacuum lines, and the air cleaner assembly will be powder coated and engine will be detailed.

Re: Favorable Crossfire Thread
Went to get a gasket for the Renegade thinking that they made one for it but, found out that they didn't. That's really the only thing holding me up til this coming Saturday. The valve cover gaskets are regular but, the VC's have a little part that hangs down that hits the Renegade. Shave that down and it will be good to go. Nice pictures KITT. Ronny, thanks for the advice on "right stuff". Was wondering what the hell I was going to have to do. Don't know much about vehicles so, the guy helping me is teaching me while I do most of the work.

Re: Favorable Crossfire Thread
When I ran XRam I don't recall using any sealant or gasket. A small leak may not matter as injectors are spraying on plenum floor anyway and sheared off with velocity. Not the best technology in fueling design there! If you remove the lid I suspect you will see fuel puddling at low corners of plenum. I did.

Re: Favorable Crossfire Thread
Been over two years since anyone posted on here. Anyone close to the Eastern Panhandle of West Virginia? I'd like to get a bunch of CFI owners and go for a cruise. Posted that on the CFI group on FB but, nothing yet.
