These are brand new 1600cc dual relief engine cases which are machined for 92mm cylinders. But, instead of being made with an Magnesium alloy - they are made of a much stronger Aluminum alloy. They have had extra material added for reinforcement and strength and are completely machined for stock configuration with 8mm and 10mm cylinder head stud inserts included. These are the ultimate BIG street engine case.
Note: A common question we get about all new engine cases is that it looks like there is a missing cylinder stud threaded insert missing on the number 3 cylinder. This thread has been deep inset and requires a longer cylinder stud. All of our dual-port cylinder stud kits come with this correct longer stud. This deep inset thread was done by the factory back in the early 70's to eliminate the problem of the engine case cracking behind the flywheel area.
We have a number of different aluminum engines cases available, all made in the same factory by the same manufacture.
