Either find a way to lower the compression, or use higher octane gas. Pinging is caused by premature ignition of the fuel, usually due to compression. Higher octane fuel is less combustible than lower octane fuel, so it's usually a good solution. With gasoline prices what they are today, using premium in an engine that was designed to run on regular is an expensive solution. You may end having to do that very thing but try some other things first. First have the timing checked to see if it is correct. If it is then purchase a can of a product called Seafoam Motor Tune. www.seafoamsales.com Put one can in the fuel tank according to the instructions on the can. I have seen this product work wonders at removing carbon deposits which can cause pinging. If one or two cans does not fully clean the carbon out, you will have to inject it directly into the intake. Do this according to the instructions on the can and follow them carefully. This should remove enough carbon deposits to stop the pinging. Pinging or pre-detonation is harmful and is something you should not ignore. Also check for any vacuum leaks, blown intake gasket, loose carb or throttle body, which can also cause pinging.

Is it an Olds engine? Olds never made a 305. Olds did produce a 307. However, once the Olds V8 went out of production, Chevy 305's were used instead of the Olds 307. If it's the Chevy engine, it will bolt right in with no modifications. If it's the Olds engine, you CAN put it in a Camaro, but you'll need an adapter plate for the bellhousing. Chances are the exhaust manifolds won't line up with the existing exhaust either, not to mention a bunch of other little tweaks that you will need to do to get the Olds engine in the Camaro, but yes, it's absolutely doable.

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.

the pressure in the engine will stop it from starting (oh 305's are shite)

Is a 2.8 liter engine a 305?

How can you tell a 350 from a 305 engine?

If you will look stright down behind the water pump, you will see the timing tab.

sure, as long as it's a Chevy turbo 400 and not a Buick, Pontiac or olds 400 it will bolt right up.

Not unless someone installed it. The small V8 in a 1984 Olds Delta 88 was the 307 V8.

There is no information on the internet about what the special feature of the Chevy 305 engine is, in fact, the Chevy 305 and 350 are interchangeable, one is just an older model.

2.8.engine size from the truck now will a 305 egine work in place of the 2.8

Yes. Beware that 305 heads usually have smaller combustion chambers than a 350, which would increase the compression ratio, possibly requiring premium fuel to avoid pinging.

Need to know the year of engine and size of engine that you are asking about. But first you need to know this. A 5.7L is a 350 engine. and a 5.0L is a 305 engine.

if you have an 84 z28 camaro it has a 305 or a 305 h.o. 5.0L

It will as long as the 305 is a VORTEC ENGINE TOO.

Either a 305 TBI, 305 TPI or a 5.7 TPI

305 cubic inch *16.387=4998 cubic centimeters 4998/1000 = 4.998 liters

In lure of saying it can not be done, I will just say. It is not logical or practical to make a 305 into a 405. The 305 should never be bored out more then 0.030 over it's original size.

The base 305 4bbl had 170, the H.O. 305 had 190 and the 305 TPI had 215

Heads off a 454 engine will not fit a 305 engine A 454 is a big block and a 305 is a small block. Even if they did fit it would probably run poorly due to low compression because the combustion chambers on the the 454 heads are larger than the ones on the 305 heads

yes it will I've even bolted a 700R4 on a 85 (305)
