EFI Rules and Carbs Drool
I'm kind of curious as to where the blocks come from that are used to build "crate" motors. I'm sure it depends on who you buy it from, but are they brand new blocks or rebuilt ones from scapyards? How do the casting numbers work, do they indicate a 04' build date if it's a new casting? Who actually makes the castings if it's not an original? Who makes the ones from Mexico I hear about?
