When refering to an engine what does 289 or 305 or whatever mean? Is a 289 a good engine? Also, what does "Stock block color" mean? Does that just refer to the paint on the block (like Ford Racing Blue)?

Thanks!

289 = Cubic Inches of the engine,
Now days most engines are in liters. 4.6 liter mustang = 281 Cubic inch if I am not mistaken.

289 and 302 are good Ford engines. 305 is a chevy engine. The bore and stroke are caluclated to make cubic inches. For example, 302 has 4" bore and 3" stroke. So 4" x 3.14159265 x 3" x 8 = 302

Yes, stock block color refers to the Ford blue paint used on block at factory.

I heard this somewhere along the line, and I'm not certain if it's true, or accurate, but the basic conversion to Litres is to divide CID by 60, correct?

Hence

302/60 = 5.0
289/60 = 4.8
351/60 = 5.9

Conversely

4.6 x 60 = 276

???

Close - Cubic inches converted to litre is to divde CI by 61.02.

302/61.02 = 4.95, so they round it off to 5.0

Thanks for all the great info! I'm looking at a '65 Mustang with a 289 engine in it.

OK, another dumb engine question.

What does it mean when they say "bored .030" over" or something like that? If it's a 302 with a 4" bore, does that mean it then has a 4.03" bore?

What's the CID on a 302 bored 30 over?

Thanks,
Ian (newbie)

Yes, that's correct - .030" over bore means 4" has been bored out to 4.030", so the CID would be 304 on a 302 bored .030" over.

Where in socal do you live? I'm in LA. I just bought my first classic mustang, and obviously I have a lot of learning to do. Any good clubs/info sources in LA? Some place that can help me restore, maintain and treat my car right?

I'm in Ridgecrest - 2 hours out of LA. I am sure someone from LA here would help you find a good club in LA. Good Luck!
