Hey guys,

I have just purchased a B20 from a 122 owner that bought it as an upgrade, which never happened, so let it go for not much money. He did not remember the year of the engine, but he did say it was from a Volvo 140. This is what I know about the engine;

It is a B20B
It has the dual HIF SUs
It has the all cast siamese manifold with dual downpipe.

I know B20Bs in 71 had a 118HP rating and 97HP from 72 on, mostly to compression ratio changes... is there a way to find out what engine I have?

Also, did the B20B come with hardened valve seats?

Now, I need to find a local machine shop to do some work on the head.

Thank you,
Marco
