350 turns out to be a 327.....
 

I just looked up the casting #'s on my heads and they turned out to be 327 heads 60cc. Is this good or bad?? Now Im curious as to what the block #'s are. It sure has a big cam in it and good power...but hmmmmm. I may have been had by this guy who sold it to me. It's definately not stock and it has recently been rebuilt cause you can still see the paint on the block. Maybe 350 with 327 heads??

Was it supposed to be the stock engine in the truck? 327ci was the large small block for '68, the 350ci replaced it in '69.

All the kid told me when I bought it was it was a 350 bored .30 over and the cam is questionable..its not a stock cam for sure...but the casting #is 3884520 on the head and the web site said 327 60cc / or 283 1960 to 1967 and 327 1962 to 1967.

they probaly put 327 heads on the 350 to boost compresion,more power...

Maybe....I thought of that also..but i will see tomorrow when i crawl under the truck to get block #'s:bowtie:

If this ends up to be a 283...It will be the most powerful 283 I have ever seen:)

Take a look at this picture........see where the fuel line runs up to the carb? Right next to the fuel line is a white arrow. That arrow is pointing to a casting number that is stamped onto that flat surface just below the the passenger side head. Once decoded, that number should tell you just about everything you need to know.

Yeah, you don't need to crawl under the truck to get block numbers. You need to crawl on top of it. The casting number is on the top of the block behind the driver's side head on the flat part where the bell housing bolts to the engine. You'll probably have to spray some brake cleaner or something back there to scrub the pad off. They're raised numbers. because of my brake booster I had to use a shaving mirror and a flashlight to read it. There was no way I was getting my head in there.

Then you need the number actually stamped into the block. 1972c10_ohio is showing you where it typically is. That's where mine was. It will have a code with letters and numbers, which end in a 2 or 3 letter suffix, like "TRW". That tells you where the engine was used and confirms (usually) whether or not it's a 2 or 4 bolt main.

Don't feel too bad if it turns out to be 327 heads. My 350 ended up having a 2bbl 327 manifold/carb on it.

I will keep Y'all posted and let you know if I have a 327/or a 350.

Its a 350 with 327 heads.....my casting #14016379 built 77-79
2 or 4 bolt main possible. Man....I was getting a little nervous at first....thought I was lied to. :bowtie:

In Texas, that menas a linchin.
