Hey gang,

1978 K10 Mr. Goodwrench 350 CID, 350 THD, Converted NP203, 3.41:1, Cali truck, EGR  >:(, Rochester Carb.

I looked for a local rebuild outfit, found two, both said to replace it with an Edelbrock, would get better mileage.

These days I wouldn't mind that!

Any recommendations?

JohnnyPopper:
Should have stated, the reason for the post is I would like to get better mileage.

At these prices it will pay for itself quite quickly.

While you hear Cali State tax is 51-55 cents, when you add it all the other 'fees' it's 1.30 per gallon.

Greetings from the land of Fruits & Nuts!!!  :(

Mike81K10:
I could be wrong! However, I have had both on my truck and did not notice much difference. I have my Rochester back on now. EFI would probably give you better fuel economy.

VileZambonie:
You won't get better fuel economy from an Edelbrock. If that's the advice they gave you then stay away from them.

What Vile said...

It's tough to beat a (good running) Rochester with it's smaller primaries for penny pinching mileage.
