Engine Block Code

Hey! I'm looking for the torque specs for a 400 main and rod caps. I'm not sure what year the engine is, but the truck it is out of is a 77. The code on the block is D7TE-A-Z-B Im not sure if that says what year the engine is or not. I'd appreciate your help!

Check the Read First: FAQ thread at the top of the 73-9 forum for various engine torque data.

Thanks a lot for your help! Just one more question. The Chilton manuel says that the main cap torque for the 1977 400m is only 35 pounds?? This seems really unreasonable cause every other spec on the page is about what Mustang81 said which seems right. (Chilton manuels always caused me grief) Anyway is that torque spec true? I've gotten plenty of different answers so i'm kinda confused

Thanks!

I took those number in the book ford performance by pat ganahl.it was for the 351 cleveland/400 cid bolt torque specification.Did your motor is stock or performance? The book give 2 torques spec,one for stock and one for performance.The one i gave to you was for stock.performance is connecting rod bolt 55 main,bering caps 95-105.In fact, it's just the connecting rod bolts torque have different number.
