We have the capability to machine your new MR-1 Pontiac block for bronze lifter bushings. This feature is available for an additional cost when you order your MR-1 or MR-1A. The bronze bushings are also an additional cost for the set. We can also install them for you.
Should you want this feature added to your MR-1 Pontiac block down the road please contact one of our authorized distributors for pricing.
