F40LM

Going to be looking at the block in my new purchase '77 this weekend.

Only the block, no heads intake etc. Just curious as I am VERY new to Corvette's.........

1. How can I be CERTAIN its a L-48 and

2. What may be a fair asking price once removed and cleaned up?

Will be going back in with a complete transplanted 350.

Thanks in advance for any advice.

first is it an OEM 77 block?? i'm sure you aren't certain, so the question was just to get you thinking. there is a stamp pad on the front of the block on the passenger side above the water pump. it will contain the engine stampings and part of the VIN number which should match your VIN tag if it's an original block. if you are talking about the value of the block alone, you need to determine if it is a 2 bolt or 4 bolt main block and obviously need to determine if you are selling it as is or if you are going to guarantee that the block is sound. etc, etc etc. i guess you are getting the point. after all of that, keep in mind that GM just celebrated the 100 millionth 350 being made, so a 77 block isn't what you would consider to be "rare" by any means. i would think that an engine rebuilder might pay $100 or so for the block, but not much more if that helps. that's just my opinion, and others may disagree.

Look at the numbers on the flat machined pad just forward of the passenger side head. There will be a VIN derivative and an assembly code with carries a suffix and a prefix. This number will give you a factory origin, build date and engine useage. A typical '77 L48 will use a suffix like CHD or CKZ. Post it here and we will look it up for you.

Let me make a suggestion that some people here will disagree with. I know in the short term, on a budget it sounds like a great idea to sell your block for $500 or so, to get more money to put towards the car if you are using a replacement engine.

IF the VIN derivative matches the VIN of your car, do NOT sell the block outright. That numbers-matching original will be worth more to the eventual future owner of that car than anyone you dump it off on now. Even though people will say the car isnt worth much now, this is a mistake people have made with Corvettes forever. Do not repeat this mistake.

Are you looking for originality? If not, you might look at one of these roller cam blocks and build a 383CI stroker.

Nothing really special about an L48 engine. It's the same engine they put in station wagons. It only has any value if it's with it's original car that it came in. If you separate it, it's just another 350 block, and they are about a dime a dozen. No, wait, I think the price may have gone up to eleven cents a dozen........

yes do not sell it, it is not worth the effort, but it will help sell your car in the future , if it is coded and stamped correctly. yes there are millions of them.. it will cost more to ship than it is worth if you sell it today.

it's a general GM 2 bolt block. about as rare as a fat kid with a happy meal...
