50mm cam tunnel option

We have the capability to machine your new MR-1 Pontiac block for a 50mm camshaft.   This feature is now available for FREE when you order your new MR-1.  The 50 mm needle cam bearings are $125.00 for the set.  

Should you want this feature added to your MR-1 Pontiac block down the road, the cam tunnel boring can be done at K&M Performance for $150.00.
