i was considering 292 in my 57 chevy pickup - does anybody know if it will fit the engine bay - someone told me it was 32 inches from the fan to the rear of the head that would go toward the firewall. i dont have that much room from back of radiator to front of firewall. is the 250 shorter?

[what i really want is that 4.2 chevy inline and have one located but too many wire bugs i hear]
