Just an update, with a couple questions.

I haven't been on here in months, have just been fed up with my mustang. Haven't done anything with it in some time. to recap: its a 67 with a 1968 302 2v.
The damn thing will only stay running for between 20 minutes and 2 days. Originally I was just going to have it rebuilt but now I may go another route.
I have found a 1970 351C for really really cheap.
The guy said it turns over, but doesn't know anything else really, as it is not in a car, and it is missing the alternator and carb.

He gave me some numbers off of it already, but they are incomplete and I am having trouble making sense of them. (the engine is kinda greasy)

Here are the numbers I have:
D0E9C485-AH ...... I think it is suppose to be "DOAE..." as that would be a 1970 Galaxy engine.

he said this one came off the intake:
0C20

He said these were on the block:
B100 D0AA

It is suppose to be a 1970 351C 2v.

Also, Are the Cleveland's good engines?
How much power stock?
Will it just drop in?
Or will I have to change things?

I only have about a day to decide, The way I see it though, with how cheap I can get it, even if it is in bad shape I can part it out and get my money back.

Thanks.
Dugan.
