I have an Indy Max block 4.375 , nothing special . Have been using my old crank down spring sleeve . Time to upgrade . Thanks for the info . Gary
Very cool, good luck with your build. Aluminum still seems really exotic to me, in spite of them being out for many
years. I started with the spring sleeve compressor too but the chamfers are almost non-existent on this one, and it
Just wasn't working too well. The old tool still works okay on stock blocks where they hogged out a .060 wide
Chamfer at the top 😂 take care
