Help decoding this bell housing !

That's not what I said:

Unless your friend has it, and is just not pictured in your original post, you will need to come up with a neutral balance 10.5" (disc diameter) 130 tooth flywheel to go with that bellhousing.
Along with the Brewer's conversion linkage, unless you are capable to fab and modify your existing linkage. (Was your car originally a four speed?)
The later, larger clutch is a worthwhile upgrade- especially with a healthy 340.
Hey buddy

He doesnt have the Flywheel just what is in the picture. I just wanted to make sure it would work as far as fitment under the floor pan. And no its originally an automatic. My buddy also has the Floor tunnel from Brewers. I plan on buying it all as a package. My 340 will be north of 450 hp so it does need this bigger set up.
