I agree it takes alot to make 900 hp but the argument was max hp possible Im not trying to build any of the engine combos . BBchevy your horse power might not be as high but I bet your torque curve skyrockets in comparison. If you look at cncmotorsports you tube videos they are pretty excited to make 700+hp on larger cubic in sbc with 23 degree heads any thing is possible with the cash$$$$
