I have a 87 CSX #174 and the question has come to mind, does it make alot of difference if the original motor doesn't match the car?? The motor that came with the car is original, but after some machine work, the bore has a bad rust ring in the cylinder and I don't know if changing motor blocks will hurt the value of the car. The car is going back to original with alot of N.O.S. parts and need some opinions on what to do.

It does to me. But I would say I'm in the minority.

IMHO.... It kind of depends on what you want to do with it. If you have it only as an investment, rebuilding the numbers block may (or may not) matter to potential buyers. If you want to put it together to have a nice car to enjoy, cruise around and take to shows or whatever, put any motor in it and take the numbers motor, lube it up and put it under the workbench. That way you'll have it if you want to put it in later, or if you need to sell it, it goes witht he car...

Matching numbers means little to me.

But then, I drive my cars instead of just parking them.

Numbers matching only matters to the Barrett-Jackson crowd. IMO I don't see these cars ever being worth the effort. I'd enjoy the car first and worry about value second.

Sounds good to me, I plan on enjoying the car as much as possible. Thanks for the feedback!!

I drove over 6000 miles in the last 90 days.

I'd keep the original block to go with the car in case you ever decide to sell. It might matter to the buyer. As for what motor you have in it while you're driving it then put whatever in.

Huh?? Of course it matters!! I agree with badassperformance, take the original block and put it away. It may not matter to you if the car has the original block or not, but it may to someone who buys it.
Yesterday I saw an ad from someone trying to track down the original block to his 1970 cuda that he sold 25 years ago, I bet he wishes he left his original block under the workbench.....

Are the block VIN stamped? How would they be identified as numbers matching? As long as you get the same year span block as the original, I wouldn't think of an issue.

Block and transmission are VIN stamped.

Where is the block stamped at? That would be awesome for identifying what year motor is in my car.

On the d-side/transmission end of the block just below the cylinder head there should be line of numbers to identify where the block was cast, car or truck line, displacement and the last 8 digits of the VIN. Sometimes they are not the most heavily stamped markings so you may not be able to read them anymore if the block was very rusty and then wire brushed it can remove the markings.
