Hi there! I have a 1932 Ford Model A with a sbc 265. I just got a 454 from a friend of a friend... I was told it came out of a mid 80s truck. I need help in reading the cast numbers on the block. the numbers to the right of the dist. are 14015445 and to the left are 324. both side of the block right below the heads has the liter stamped of 7.4. Also, when I look for parts i'm asked what generation is it? I think it is a Mark IV. Please help!

I can't really help you with the casting #'s but you may want to change your post title to something like "454 casting numbers" to generate a better response
 
14015445 is indeed a Mark IV block. I have a 5445 block that is 4 bolt main but I've read that casting can be either 2 or 4 bolt.

Post up the casting # from the heads and we can tell you more about them also. If it's just a cruiser pretty much any head will be fine but if it's going to be a thumper then some heads don't flow well enough (the ones with my 5445 were not the good ones).

I'm not familiar with this casting but I'd bet they are the late model "peanut" port heads that are less desirable for performance applications.
