Dear Subscriber,

This month's Performance Professor Lecture "At The Core of Carburetion" will be available for download tomorrow (7/14). Below is a portion from the introduction:

"This lecture addresses the fundamentals of carburetors, their benefits, limitations and reasons why they’re still a popular bolt-on item. Some proponents of electronic fuel injection tend to look upon carburetors as "dinosaurs." From a technology perspective, they may be. But when you consider some of their cost-effective features and the range of contemporary refinement available, today’s "carburetors" are a far cry from versions introduced decades ago."

The Professor's interview for this lecture is with Barry Grant, President of Barry Grant, Inc.

Make sure to post the rest.

IMO, carbs suck. If i had the money, i would drop in an EFI system. From my reading, there isn't an improvement in power. They both are capable of generating X number of horses when set up right. The biggest advantage is fuel economy. Couple an EFI system with an over drive tranny and you have a classic car with moder tech giving you over 20 mpg without sacraficing anything buy the wallet.

I differ. A properly setup engine with a carb will deliver similar mileage as EFI on the highway, at cruise and will be close to EFI during stop and go driving.

There's more to mileage than the fuel mixer. Quench, compression, cam match to head flow, exhaust pulse vs cam overlap, etc, all are equal players in fuel mileage.

My old 350 delivered over 18 consistantly and twice 22 mpg on the highway. That was with better flowing heads, tighter quench, and 1.6 rockers on the exhausts to clear the cylinders better.

Buy a 4 cylinder? You're off the wall man. I have a 95 Vette that does around 27 mpg highway, and if I wanted better I'll buy a C5.

It's purely a matter of effciencies. As I said once or twice before. I can use my time and money to build a 450+ hp car just as easily. But guess what? There's always someone faster. So I enjoy my 230 hp and get a thrill out of boosting the mileage. Anybody having a problem with that can

That's a fine looking ass, Biltogo. Can I use it next season to help plow my fields?
50 cent an hour rent, you pick up and return. Methane mask optional:cheers:

Im talking about older C3's that are carburated, I am just saying they should be left alone....... keep them the classic cars they are. I have a 2002 Ford Lightning pickup that will take care of the faster cars out there. Then I like to watch the passengers of these cars laugh at their friends for getting beat by a truck. Now I am waiting for the 500hp Lightning's to come out :D

carbs

hey guys,
i know this is a late post, but just to give my opinion. If you want power then the carb is the way to go, if you want fuel ecomomy then go efi. I have been racing for 10 years now and have seen time after time that a carb will out do a efi on the track.

Fuel economy? I have had 3 4x4 trucks. The first with headers, holley carb, cam and distributor work, it was a 350 and got 16 mpg.
Next was a ford 302, totally stock fuel injected and it ran 11 or 12 mpg.
Next is my Dodge 318, totally stock, fuel injection and runs around 11 mpg.
Tell me fuel injection is more economical???:surprised

I had a thermostat on the dodge break sticking open. The motor never heated up off of cold since it was winter. Left it that way for a month, hard on the motor running cold all the time but mileage went up to 16-17, driveabilty went up, no heat though and hard on the oil so in went a new thermostat, mileage dropped to the 11-12 range.

The fuel injection runs too lean for good mileage but it is need for NOX emissions.

NO give me a good carb that is tuneable and keep the injection.

Simply put. Carbs leak and taint the oil

Simply put. Carbs leak and taint the oil.:bang

Those little 'freeze' type plugs expand and contract at a different rate
than the casting(s). Thus allowing gas to get by and into the oil.

Then there are the sticking floats.:devil:

Reminds me of a 68 big block parked nose down on a hill at a club
social event. Upon leaving the engine would not crank. Lights and
accessories were in good order. Found the cylinders full of gas.

Had to go get a trailer to get it home. :rolleyes:

5, 10, or was it 20 years later?:lookinup:

Again, parked nose down. But, with his spouses 67 big block.
Same event . Same hill. Uh Huh. Same problem. I even think it was
the same trailer.:rolling:

My 68 big block (NOT the same as above) was short blocked by GM
under warranty for it. Yep, they put the quadrajet back on it!:thud:
