I've got a 1984 Camaro Berlinetta. Swapping in the 350 from a 94 suburban. Took the carb and intake manifold from the 305 and bolted everything on. Intake manifold is gonna have to be changed cause the four center bolt holes don't line up with the cylinder head bolt holes. I've decided to stick with carb for several reasons. I don't plan to make more than 350HP, gonna set my rev limiter to about 4500rpm, I don't travel far so fuel economy doesn't matter, this is mostly going to be a daily driver or sometimes a show car. I've already got an Edelbrock 1406 carb, a Edelbrock 4-7 PSI inline fuel pump, and an Edelbrock billet fuel filter. So, what would you all recommend to optimize my system to put out as much power and efficiency as I can? Should I go high ram or low profile, single or dual plane?

 

Read the Edelbrock instructions for their carb. It's all in there. They're fairly good. Not gonna retype all that sort of thing here.

 

Power, efficiency and edelbrock carb should never be in the same sentence. Your best bet to make it run decent with that combo is to get a dual plane intake, wide band A/F gauge and vacuum gauge and tune the jets, rods and springs per the carbs manual

 

I'll second the AFR gauge, I wont go back to tuning a carb without one.

 

Man you are all over the place with what you are wanting to do with your Camaro Berlinetta.

If you don't sit down and make a rock solid, well thought out plan. and stick to it you are just going to end up making a mess.

Your 1984 Camaro Berlinetta has an LG4 engine with a 4 speed automatic overdrive transmission, an electronically controlled lock up torque convertor, an electronic feedback Quadrajet carburetor, a computer controlled large cap HEI distributor, and I assume computer controlled A.I.R. diverter valve, EGR control solenoid, and EFE valve.

What are you going to do with all the stuff controlled by the Computer Command Control ECM when the electronic feedback Q-jet is gone and I assume the C.C.C. ECM with it?

You are going to have to convert it to a Canadian export model LG4/700R4 without Computer Command Control, or ditch everything controlled by the ECM and go full old school with an analog carburetor and mechanical/vacuum advance large cap HEI or similar distributor.

Didn't Colorado adopt a bunch of California's dumbass emissions laws and rules? Doesn't Colorado have emissions testing? Maybe your area of Colorado doesn't have emission tests or you are exempt from them due to the age of your car, or antique plates, registration, and insurance.

"With an average altitude of about 6,800 feet above sea level, Colorado is the highest contiguous State in the Union. Roughly three-quarters of the Nation's land above 10,000 feet altitude lies within its borders."

I assume Colorado has 4 seasons of weather and different elevations within the State and you might want to visit some of the surrounding States that are at a lower elevation than Colorado.

You want to daily drive the car. I assume you don't want cold start issues or cold drivability issues and don't want drivability issues due to elevation changes.

Your stock C.C.C. system can deal with all of these things with its sensors, mixture control solenoids in the Q-jet and computer controlled HEI distributor. Plus the heat stove for the air cleaner, exhaust heat crossover in the intake manifold, A.I.R. in the exhaust manifolds, and EFE system. With MAP and Baro feedback to the C.C.C. ECM and an O2 sensor. I can't remember if these earlier cars have knock sensors and electronic spark control modules but if they do it would help too.

With slight modifications to the stock LG4/L69 intake manifold's 4 inner bolt holes everything under hood can bolt right onto your 1994 L05 engine or you could replace it with a Edelbrock Performer 3706 intake manifold and 98% of everything under the hood would just bolt right on and the other 2% might be some slight trimming of some brackets.

A completes powertrain swap from the 1994 Suburban would do everything the C.C.C. system can do and more and way better too.

Now lets talk about modern gasoline. It absolutely sucks when used in a carburetor at high altitudes being pulled from the gas tank under a vacuum by a fuel pump. High altitude = lower boiling point, being pulled from the gas tank under a vacuum = lower boiling point. Todays gasoline isn't formulated for use with carburetors. It's formulated for higher pressure fuel injection systems with the fuel pump in the gas tank staying cool submerged in gasoline and pumping the fuel out under pressure not a vacuum. It's got 10% or more ethanol content and that is subject to be 15% or more in the future. It doesn't have the stuff in it anymore to raise its boiling point or decrease its evaporation rate.

GM's reliable TBI system at 11+ PSI of fuel pressure won't be subject to any of these fuel or altitude problems.

OK rant OFF.

I'm sure there are misspelling and grammar errors. My mind is tired and I also don't care either.

 

^ That was a good rant...
