Build your next engine with peace of mind - Start with a brand-new AS41 Magnesium Dual Relief Universal engine case!

Old engine cases are often worn beyond repair and have an accumulation of hidden defects. Sure, you can align-bore that old case, but where do you actually begin and end the search for cracks, pulled studs, worn bearing saddles, warpage, and loose oil galley plugs. Many of these defects are only found after attempting to run your new engine build.

New engine cases are equipped with steel case savers for use with 8mm studs, factory installed main journal studs, case half studs, and oil pick up tube. The main bearing saddles are factory standard.

Universal means it not only fits Type-1's, but it also has the mounting holes for a Type-2 Bus installation, as well as the dipstick hole for a Type-3 (Universal Case/Type-3 Block Offs are also available).

Also available, the Ready for Assembly CB Super Case.
