351W Nothing adding up. Please Help!!

Hello all, I want to start by saying if this was covered already I swear I did look and was unable to find it. I have been lurking here for months and well decided I like the crowd and want to join.

I have a 1989 F-150 4x4 with a 351 the guy who swapped from a 302 was an idiot and didn't change oil pan or anything just through it together and now I am paying the price. It is my DD so I am in the process of building a 351W on the side for a weekend drop in and am getting conflicting dates and numbers so am wanting to CYA before I order a crap load of parts.

The Casting # on the block is E4AE-6015 which if I am correct means 1980's
The manufacture # is 5E6 which again if I am correct means May, 6 1985.
(I stole all this knowledge from this forum so I have been researching and am at wits end .)

The block does NOT have an oil dipstick hole in the block which I was informed is incorrect for the year of block. I have double checked Casting number for accuracy and am 100%. I have a timing cover with the dip stick hole mounted in it.

My questions are as follows:
Does the casting # and dipstick location coincide with one another?
Will the timing cover dipstick work with the truck oil pan and pump?

Mid '80s pickup motors had a dipstick in the drivers side of the oilpan and the vans had it in the timing cover If I'm not mistaken so either should work.

Ok, Thank you so much. I was under the impression that Ford phased out of timing cover dipsticks in the mid 70's so that was why I was confused.

Well for one thing, he did change the oilpan, a 351W pan will not fit a 302 block. The casting numbers have nothing to do with the oilpan used from the factory, that same block was used in all applications equipped with a 351W

also that year 351w your planning to drop in is a pig of a motor. what are your plans for the build because you will need to take into account how the efi will handle different things.

also what more in detail can you say the guy did wrong with the motor swap? with all due respect perhaps you dont fully understand whats necessary to perform that swap. ive done the same motor swap on an 88 bronco and depending on the year of the 5.8 used, different changes would need to be made. also if that current motor is a 94+ year motor it would be the better choice to rebuild.
