We are pretty sure that our engine is a modified 283 engine with different valve covers, but I just want to be sure it's a 283.

Really, Damn I thought my 1962 had its original engine in there. Our engine is a small block, is that engine a small block?


These codes are the last 2 digits, correct?

Another question, What do the numbers on the back of the block represent? I ask because we haven't checked those numbers yet.

Eric, last two digits "MA" is the engine code. And yes that would be a small block. 210 HP would of had a two barrel carb. Here's some casting codes http://www.chevy-camaro.com/chevy-camaro-chevy-en g... these are on the back of the block to help identify it also.

Did 1962 trucks come with a 327 out of the factory? Or did somebody swap it in there?

Somebody swapped it in there. It's ether a 1967 Or 1968 engine.

The numbers at the rear of the engine will include a casting date code, and that will tell you the actual year the block was cast. The stamping at the front of the engine tells you only the month and day the engine was assembled, but not the year.

Ray, I looked in my 60-66 chevy truck factory assembly Manuel and it says under "type destignation" that MA means a 1962 283 engine that has trademaster with powerglide.

So is Brian correct about it being a 327 or can "MA" on the front of the block mean a 283 with a powerglide?


We are sure that ours used to be an automatic since its got an automatic radiator and an automatic column on there.

Some stamped assembly codes were used across a fairly wide range of years. That's exactly the reason you want to look at the casting date. The casting date is the actual year the block was made, unless some practical joker at the GM foundry wanted to mess with your mind 50 years after the truck rolled out the door.

Eric, I did some more snooping on the internet, and found where MA could be a 62 283 truck engine.
Hope I didn't mess you up with the previous posts. I was just trying to help. Sorry

its fine, I appreciate the help, because now I know what to look for and now I know the engine could in fact be a a 327 and not a 283.

Not to do anything but clarify here. I was on the farm in 1962-1967. We bought a new 64 Custom 1/2 ton. It came with a 283/glide. The next year (65) we bought another exactly like it, with the exception that a 327 was available. Dad bought one with a power glide. We thought that was the baddest truck ever built.
Little did we know that the famed "big block" was coming.
Just my two pennies.
