HEAVY DUTY FRONT CAP
For some extra strength on the front main bearing on several different engine platforms, you can narrow up a beefier 4-bolt cap to fit the 2-bolt register. If the radial depth is close enough to be able to “hone-in”, you often don’t even need to rough bore them. Here’s an example of a nodular 4 bolt Chevy cap, modified for the front main. It’s around 50 grams heavier and the material is almost 3 times as strong as the stock cap. This is great for rule legal applications where factory caps must be used.
