78 longblock question
I am replacing the engine in my sons 1970 F100. I know that the engine is a 78 351w, do I need to know what it came out of before ordering the longblock? The dipstick is in the front right side of the block. I will be replacing the intake and carb also so I'm not too concerned about the intake matching up.

If you want a new longblock that's close to what you have, just the info that it's a '78 should be sufficient. But you might want to consider getting an earlier one so you get the better heads, unless the rebuilders are particular about getting a core back that's exactly the same as what you bought. Might be able to upgrade for a little extra moola. '78 was not a great year in terms of heads. Low compression, smaller valves, low power...'70 through '77 were much better.
