BREAK-IN PROCEEDURE (click here to see how its done)
All engines are pre run for 25 minutes with outer valve springs only,
using a premium petroleum based engine oil containing 8 oz of Red Line's 'break-in' additive.
Inner valve springs are reinstalled.  Engine is run again to adjust valve train and set timing.

Engines are sold 100% complete and assembled, less carb and valve covers.

following options, all available and installed during in house engine break-in;
*Choice of top brand carburetors*
