My friend just purchased an 83 camaro RS. He was told that the 305 had been pulled and a Crate 350 was installed. We got it home and looked at the casting numbers:

Block: 460777- 78-79 305 block
Heads: 333882 74-80...350/400......76cc chambers

This has obviously been pieced together and appears to be a 305.
Can a 305 block be bored out to a 350? .24 of an inch seems like quite a stretch, considering I have a 305 thats bored .040 over. Im sure this happens often, people trying to push over a 305 as a 350. Please let me know whats going on here, and if theres anything my friend can do. This car is even advertised in autotrader as having a 350 in it. Thanks.

You can't bore it. Once a 305, always a 305. Might want to talk to a lawyer about it.

 

dang. that sux. did you or your friend get back in touch with the seller? id be interested in hearing his response.

 

Was the car running when your friend got it?
If so it must have been awfully slow with 76cc heads on a 305. Even with flattop pistons, it would have about 7.75:1 CR.

 

We left a message with the seller... yes the car is running, and is terribly slow. Ran it again my 98 Cherokee with K&N and muffler, and I beat him buy a carlink, and I have the 6 cylinder. Its hilariously slow. I also cant wait to hear this guys response. Ill keep everyone updated.

 

That guy has to be assuming that the buyer is a complete fool, or he's left town.
And if he hasn't left town, that makes him the fool.
Unless he's got mob ties.
