Does the 1987 Caprice Classic 5.0 carbureted have a Chevy 305 engine or an olds 307?

A 1987 Chevy Caprice Classic with the original engine does have a carb and the engine is a 305, because I have one. This can have a 307. I have an 87 Caprice Estate Wagon, with a 5.0 liter 307 olds. Which, is actually for sale.


Can you use a 1974 chevy 307 c.i. egr equipped carb and intake on a 1969 chevy 307 c.i. engine with non-egr heads?

Sure. Although the choke will at the very least, need adjusting if you can get it to work at all. You might need to adjust and/or re-jet the carb as well. But assuming that the carb is good, you can just bolt it on and it WILL run, just no telling how well it will run. I've done it before with no mods to the carb and it ran just fine. Other times, I had to fiddle with it to get it to run right. Since they are both 307's, chances are it will work just fine other than the possible choke issues.

WHich motor is better 305 or 307?

There is basically no difference. 305 is a Chevy engine and the 307 is a Cadillac engine. They are both the same and assembled by same company Well, on the other hand, it depends on how you look at it. The 305 Chevy is a 265 stroked with a 350 crank. The 307 Chevy is a 283 stroked with a 327 crank. In theory, the 305 should produce it's best torque at a lower rpm than the 307. However, the 307 should be able to rev higher and produce a higher peak horsepower. Kinda depends on what you need it for. There is also a 307 produced by Oldsmobile that is a V8 engine. It shares no other commonalities with a small block Chevy.

Will a carburetor from a Chevy 350 fit on an olds 307 manifold?

Most Rochestor 2 and 4 barrel carbs should fit on the manifold but watch out for subtle linkage and choke hook ups. And the carb off the 350 will be a bit rich for the 307. Short of changing the metering rods, it's tricky to lean out.

Why does a 307 pop from carb?

Could be a number of reasons but one that comes to mind is the camshaft has worn lobes. This condition would cause a consistent popping out of the carb on acceleration.
