I just bought a car the old owner said had a 350. The engine has TBI. It is not the original engine as the car is a 63 Impala. Previous owner had very little real knowledge of the engine. The date code on the block is H178 so it looks like it is a 1988 engine. Block casting number is covered by the Powerglide kickdown bracket. Engine code is V0823TPN which does not exist in any of the Chevy engine code web sites I have visited. I want to put a new intake manifold on the engine but want to positively ID the engine before I order the manifold. I can pull the bracket and get the block casing number but that would be a big pain, as there is not much room behind the engine. Does anyone know of any other way I can verify the engine I have?

The casting number will give you more information. Assuming it is a 1988 block, it could be a 305 or 350. I would NEVER go by what someone "says" because it can be incorrect.

If it is a 1978 casting, then it could be several small block engines.

Remove that bracket and take a pic of the casting number.

People fear change because it threatens what they know, or what they claim to know.

Thanks. I will remove the bracket to get the info.

Several years ago, I helped a friend who was going to buy a 1978 Chevrolet Camaro. He asked me to look it over. I noticed that the engine was red/orange, not blue, like it should have been.

The guy selling the vehicle insisted that it was a 350 out of a 1970 Camaro and was a 4-bolt main. I questioned the 2-bbl carburetor, an old Rochester 2GC and he insisted that he put the intake on for better mileage.

So, here stands a guy lying through his teeth insisting that it is a 350. I got my light and phone behind the engine and photographed the casting number.

Turns out that it was a 307 engine from the early 70s. Definitely not a 350 even though my friend was assured that it was.

Believe nothing.
