After 2 years of searching almost all the junk yards around I finally found the 400 block I was looking for. Do not become surprized, mopar parts are toooooo rare here in Iran. 318s and 6cyls are everywhere but big blocks and in particular 400 is very rare. It is a 74 block with standard bore size that had a 2barrel carb from stock so it didn;t experience extreme stress in its previous life (let me warm my heart at least). It seems to be a clean item but the bad news is that one of the rods was brocken and damaged the very lower edge of two cylinders. I showed the block to two expert mechanics and both confirmed that it cant be a problem even if stroker engine is to be made. Another bad news is that there is no sonic test facilities around and I am unable to measure the wall thickness but I wana trust it becasue I have read many articles saying that 400block is the strongest block of all Mopar big blocks ever. Below are some pictures with explanations:
Lower deck of the block
Cranck retainer number 2
Crank retainer number 3
Block casting number
Block date code
Tranny's casting number. On the rectangular plate it reads PP833 3388 and the letters on the right side are not very clear but I guessed 7G235273 and 00 14 below it!
Tranny's tail casting number
Tranny's other side casting number. Can anybody give me some information about this tranny? What is the model year, gear ratios and etc? It was on the car when I purchased it but the car was originally equipped with a 727 and the previous owner exchanged it with this 4 speed and so I know nothing about its history
The damaged edges of the two upper cylinders. Any comments on this?
Someone tells me what this rod that goes to the cam is used for.
I am looking forward your useful replies ASAP.
