You pull the old sleaves out and have the block counter bored to take the larger sleaves(Darton sleaves).4 1/2-4 3/4 bores are fairly easy to get. Also Have the crank offset ground to 4 1/4 inch,with 4.1/2x4.1/4 you will have 405 cubic inches.

Darton will make the sleeves to the size you want.Call them, they will ask you for the specs and go from there. Talk to your Machine shop first then call Dartons #toll free 1-888-877-8484
