Quote: I'm sorry, let me try this again. I want to take the oil pan, pickup tube, heads and water pump housing from the 383 and put it on the 413. Did I forget anything?
YES ... it will work .. but you can do better. Get a set of small chambered heads for more compression(the MH 413 is very weak in that area). And a set of regular 383 heads(906's?) will not help.
In this swap ... watch out for the top two ports of the water pump in the block. On the 413 - using those "goofy" heads ... these ports are more-than-likely plugged with sediment.
