well it depends on the year, i think at around 85-86 they changed to a 1 piece rear main seal instead of a 2 piece but otherwise yes you can put a carb on an efi engine or vise versa.

I recall hearing that Mexican castings in the mid 80's were more desirable...not sure why, maybe a better grade of cast or something in the design changed?

There eas a higher level of some alloy in the block that made them just a little bit stronger.

I have heard different. The mid or late 80 mexican blocks I heard were more porus in the casting and thus were less desirable. However I do know that the late 60 early 70 mexican blocks were desired because they have a different alloy content and are the blocks that have the thicker main bearing caps. I have a late 60 mexican block so I know that part is true but I have only heard about the 80 blocks.

Thanks guy's. I went a head and bought the block. The person I bought it of bought it at a yard sell a couple years ago. The person he bought it off said he bought it from summit racing. They advertised it as last of the new 302 blocks. It is new the numbers I found on it are 5F21. Any Ideals what year block it is. Also came with summit racing cam 3600 and ford motor sport crank H-6303-A50 all new in the box. From what i seen on the cam it isn't a roller cam. Is it ok to use with this block. I do a lot of 4x4ing in arizona so i want to stay with carb. I carry most everything i need to fix most problems of road that is why i stay with the carb.

Dont know about the numbers, but being the last of the New 302 blocks could be. In 2001, I hauled the last casting machine for the 302 motor out of Cleveland Ohio to Kansas. That was fun, backing a 6axle heavy haul rig into the Ford plant there.
