351w roller vs 351 non-roller blocks

[Pman1961]

Okay, sounds like the acquiring of the short block is a done deal. The reason asking about the lifters is to keep costs down. In my mind I have to justify this some how or another. I saw on the Internet were you drill approximatelly 3/8" deep in the lifter galley and then tapped threads. The hole did not go through the block. The oil return holes were temporarily block during the procedure to prevent material from entering the block. This mod was done with the engine in the car. Now a new question and I may need to start a new thread but any one on this forum have a 408 and are happy with their build or would you have done something else as far as combinations goes. In others words dual plane or single plane intake, heads, etc. I'm going to contact and purchase my items from Keith Craft such as cam, heads, etc. Thanks again everyone! Oh by the way. It looks as though I'll have some parts to sell....short block, heads, roller cam, possibly intake & carb.
