MRL Custom Main Caps SBM
Well this has been in the works for some time now and I finally have a set of "prototypes". These are custom made and are designed to work well with a main girdle.
When you get a SBM main girdle, you have to do a lot of shimming. And there is a way to install them by milling the bottoms of the caps to make them all flat and even. This gives the girdle a "pad" to sit on the cap directly. I have done quite a few of these, and never really liked the way the whole thing works. But its better than just the stock caps alone.
I dont much care for the main caps that are out there for the SBM, so I designed a set of my own.
They are made from 4140 steel, have a tight fit to the stud(stock caps are sloppy at best), and have a much larger contact pad for the girdle. They are also custom made. If you have a register in the block that is larger than normal, or if you need to have the register cleaned up on the Mill. We can make them to fit your block.
This setup will make a stock block jump into the higher rpm/hp range without going to a $3000+ MP or Ritter block. No, this will not make your block as strong as those blocks, but its a good in-between option. Add 4" of Hard Block and you will good for 700hp, or more if you keep the tune good(No detonation). Light rotating assemblies and a good rod ratio help push the stock blocks to these higher power levels.
I will get pricing on here if there is some real interest in this. We plan on selling just the first 4 caps and a cap/girdle combo with studs.
As of now, I only have the 360s done. 318/340 Coming Soon!
