BMW's Big Sixes are precision machines which require and deserve only the best preparation to ensure the longevity we've grown accustomed to with these engines.
Proper machining and assembly is crucial to the success and longevity of the Big Six in any application, from a stock rebuild to a full race engine. M30's, taken to a performance level they never saw stock, also benefit from this preparation.
The VAC Engine Block Torque Plate 'loads' the block as if a head was already fitted. This torque applied to the block simulates the final assembled product and ensures that the cylinder walls are bored and honed perfectly round when final assembly is complete.
If you're rebuilding an M30/S38/M88, this is crucial to ensuring the best finished product.
