Update : We have a new BMP block!! A very nice guy on facebook , who ordered one in fall of 2020 and got it this year put it up for sale as he picked up a built 605 with world block and is happy with his set up.
So, Christmas complete on the block. Now its getting bearings, pistons/rings, machine work and built.
Thanks to everyone.

Question: i see differing comments on compression loss with aluminum blocks : Is that a real issue at 775-800 hp range or just for more intensive combos. Yes we will hone with plate/correctly etc .
Secondly, using race fuels ( C12) anyone know what temp range is best target ?

Thanks in advance.
