48 Degree R1A Block w/W2 Top End

What is a 48 degree block? I was under the impression that virtually all V-8 used a 90 degree block. Feel free to mock me about my ignorance ;)

I'm just curious, this seems like a great deal, and parts look top notch.

Best of luck with the sale.

48* lifter angle Joe. Versus the 59* stock production angle. Provides a straighter pushrod angle toward the heads, and is really helpful when large lift cams are used.
