Thread: Carburetor or Fuel Injection

Tweet

I'm finishing a 1937 Dodge pickup built on a 1989 S10 frame with a 1990 350/350 turbo, I built this truck as an every day driver and plan to drive it for years to come. My question is about what type of induction would get me the best fuel economy, carbureted or fuel injection, I'm looking for maximum fuel economy not performance. I may change the tranny to a 700r4, don't know if it would help the fuel economy that much.

It currently has an Edelbrock Performer intake and carb on it. The engine was a rebuild or possible warranty engine I pulled from an '87 Chevy pickup, it has a roller cam and rockers and is around 200hp.

Could I get better fuel economy from a stock GM TBI or TPI system, what about one from Holley or Edelbrock, they show up on ebay for a few hundred?

The last car I built was a 1930 Model A Tudor old school hot rod with a stock 4-bolt SBC with a Performer intake, Holley 650 and a 5 speed out of a Camaro. This car weighs about 2300lbs but only gets around 16-18 miles per gallon, usually less can't seem to keep my foot out of it.

Is it possible to get an average of 20+ miles per gallon out of an early SBC?
