I have built and raced both small and large the bigger a little motor becomes the more heat becomes a problem unless its on alky a large BBC with alloy heads and 9-1/2 to one will run on pump fuel well some times these days and will make up the difference in weight / power --- a special fuel large small block is a pain to control with heat and detonation / verses the power you get they need much more in the way of oil clearence rings rods and mains and a special anti cavation ( anti spark oil pump ) that limits your cam choices YET i have seen many 800-HP and more SBC motors some last and than theirs the others their is no Substitute for cubic inches the bigger the engine the less effort to go the same as a small real high effort combo its all in the numbers ( MATH ) my 2 cents for what its worth jz
