tbi block in my 84

[84Longbed]

The 350 in my c10 locked up. I found a great deal on a 88 350 tbi engine and im going to just put my edelbrock performer rpm intake and carb on it. My question is with the fuel pump. The 88 block has the fuel pump block off plate which I have already removed. It has the hole going down into the block, Im just wondering if I can take the mechanical fuel pump and rod out of my old 350 and put them into the newer block. If so, how is it done? Also I need to buy a timing set for the tbi block and i dont kno if they differ from pre 87 timing sets. Thanks for any help
