Default 402 engine

Hello,
I looked at 68 big block vert. The car doesn't have the original engine but it has a 402 in it. Is this a good replacement for the 427? The car has big rear flares and 10" wheels on the rear. It is all there but will need some TLC. There is no rust on the frame or windshield posts. I am seriously thinking of buying this car, but I know nothing about the 402 engine. Any and all help would be great. I can get the car for 11k.

Tony

Still a big block. I know that all '70 SS 396 Chevelle's were actually 402's. Marketing dept. thought the 396 was so well known that they just kept it that way. Can't remember why they went to 402 cubes.

It was a marketing thing to keep the "396" identity. Nothing wrong with the 402 (or 396 if you prefer) that I've heard of.

The 402 is a 396 that was .030 bored from the factory. They are very good motors and were in some Camaros also.

As stated above the factory cast 396 's might have been a little off , so they honed the cylinders to .30 over to salvage alot of blocks....

Good candidate for a 502 swap if you are so inclined. All the exhaust is there, pullies and brackets, etc. 402 is just a little big-block. Nothing wrong with that.

The 402 (396/375) is a good engine, they were fast and reliable. Knew someone that had one in a factory SS Nova 68 or 69, it was a rocket ship. Good luck.

If the car is solid, buy it at that price.

I am going to make him an offer. The car has monza style headlights. He has all the original headlight parts and said they should bolt right in. The car had factory side exhaust that he took off. Again, he has the original covers and pipes. He says that the rear spindles need to be greased. The last time the car was on the road was 1 year ago. Does anyone know if the headlights are easily bolted back in? I know I will have to redo the vacuum lines. When i was under the car I saw no rust other than the usual surface rust. The windshield post was perfect.
Does this sound like a deal?

The Monza light kits were supposed to bolt in, so I assume you can unbolt them and bolt the originals back in there. As long as he didn't modify the openings or the brackets, you should be good.

The factory side exhaust were on everything from '68 up to '82, but they were only available originally on the '69. Keep them, you'll love them. If not, I'd like them.

The vacuum lines may not be as bad as you think. Get a can of starting fluid and squirt it around the hoses. Any vacuum leaks will be detected by the engine running faster.

Often, you can pull the hose off, clean the connection, and put them back. You may have to trim the hose back half an inch to get fresh unstretched rubber.

Dr. Rebuild seems to have the best hoses if you need new ones.
