I am looking for a picture of a 1991 chevy engine. I want to know what is the round thing next to the carb.?

Go to your local auto-parts store and look in a repair manual (Chilton's or Haynes) for the year of the vehicle.\n Like the other has said it is probly the EGR valve. Or  a vaccuum valve for a cruise control. Anyway it should not be shaking. And holding it still causes the engine to run smoother? If this thing does not have any wires runninig off of it. Then it has a vaccuum leak. Reattach it to be solidly mounted or replace it.\n If this is a vaccuum valve then there should be a diagram of the vaccuum hose layout on a sticker under the hood. And this component should be named in that diagram.

It is not exactly round, just looks that way.\n\nSee webpage below for the correct shape.

A good high performance carb would be a holley . you can get them at a few auto parts stores or you can order them online at Jegs or Summit racing.

Hehe, I answered your motor mount question first..... Yeah I don't think it's the motor mount but you need a mechanic to do a test drive, don't expect anyone to give a proper diagnostic over the internet.... not even in the parking lot looking at the vehicle!

Check eBay motors. They have a section dedicated to parts.

Ebay always has chevy truck parts... Only bad part is if your looking for parts on a truck thats 1988 or newer, you have to look through a million pages of tailights.

Hi.Sounds like a head gasket [hopefully not a cracked head]or screwed up], a mechanic could  do a compression test on your motor  that's a tell all sign or even check for leaks comming out the side. When your car is running is the  exhaust white like -steam? If the car is a 4 cylinder  straight 6 not to bad $, but V6 , V8 ENGINE and the cost gos up .Water in the oil is no a goodthing[burn out the bearings+ piston rings....] you'll will destroy your car if you don't get this repared  250-450$ and thats if its easy from a shop

USMANCA- If you don't have an answer then just shut the hell up and quit wasting space. \nAnyways, its going to be kinda hard b/c you're most likely going to have to modify the motor mounts and tranny mounts. And rearrange some of the other parts in the engine bay but it would definately work. You might want to go to a Chevy shop and see what they tell you as far as the logistics of what you're looking at. You might also want to switch the gears out in the diff. B/c of the weight of the truck taller gears will take the strain off the block.

i have never heard of such thing but i think you are talking about a multi carb set up witch gives you more fuel and more air at the motor

If it doesn't bolt up your 5 liter engine is probably a Buick, Olds or Pontiac 307 not a 305.\n  These engines have a wider block. The intake manifold is a couple inches wider than the Chevrolet version.\n   GM installed these engines in some Chevys. They also put the Chevy engines in B.O.P cars.
