There is another designe of Liners that we could use,I will be looking at the engine and seing what broke then look at a fix,
Also this was the original block we used in Rods old 500hp engine so it has already done 25k with 500hp and 5 of that was with 75hp nos, and 10k on this engine so we may also have found the life span of this block and mods.
