ok,
my 68 camaro has an engine from the mid 70s in it, I think, as far as I can trace the numbers. I have a 1968 - 327 I took out of a 1968 impala, would this motor be considered a match for my 68 camaro ??

 

Anyone would love to have a matching numbers car. If not, a correct displacement engine in the car. A correct displacement engine and correct date code is about as close as you can get to being a matching numbers without actually having matching numbers. Sounds like you have a winning combo to me.

 

"Period correct", but not car correct is what the engine might be if the date on the block falls into the same time frame (assembled before the car) as what the original engine was. "Matching numbers" means the engine has the same partial VIN as the body. Matching numbers, once lost, can never be had back again legally, unless you found the needle in a haystack missing block.

 

depending on when your camaro was built (like early in the year) you might have to look for a motor that was built late in the year before. so a 68 built early in the model year will have a 67 motor in it. so do you know when your camaro was built?

 

I do not know the date of build

 

This will show you how to find the numbers you need to: Camaro Decoding help on Chevy-Camaro.com

 

will try to fig it out

 

I have the protecto plate book it says car was put into sevice 4-30-68
would that be when it was built ??

 

That's what that would mean. Do you have the plate too, or just the book it came in?

 

I have heard the term "Numbers correct" . You are doing this because you want a car that looks correct? I have never seen any evidence that a Numbers correct car is worth mpre then a car in the same condition with a well built motor from the 70's.

The people that pay big money for cars are your collectors and your show car people and neither of them would look twice at a "numbers correct" car.
