I have never heard of a 2450 before this. I looked at race Eng. and esslinger both and didn't see anything like that. Could be something they used in the Pro4 Trucks or boats maybe?
Dave..... I worked the math. The first is the Esslinger new/outstanding block. With their max recommended bore of 3.940". The 2nd is a standard block with a +.040" bore @ 3.820". The Essy block would require a 3.065" crank stroke for 2450cc total engine capacity. The +.040" bore standard block would require a 3.261" crank stroke for 2450cc total engine capacity. Questions? -Dave-
