Bought a 70 formula 400

[beemerten]

Bought this one a week ago. It is not the original engine in it so i hoped someone could help me to identify it. Here are some numbers:

Below the heads at the front : 0323464 With a YT below it

Number at the distributor : 0095

Number at the heads : 0235


Any help will be greatly appreciated

Thanks for the site! But i dont know what a strange kind of engine i got,i cant find my number at that list...

Well the YT code was listed for many engines but you have to find the casting code to narrow it down. The same site shows you where to find the casting code.

Finally found that number behind some old dirt. The engine is a 400 from 75.
Got a new question for you guys... I am from Norway so i dont understand all of the words i read.
This words was standing in the column for casting codes: Casting # Year CID HP Main Notes. I was wondering what the word main means.
