351w roller conversion
I have a 70s model 351w that I’m building and a 92 302 that’s shot, my 302 has a e303 cam that I want to swap into the 351 along with the roller lifters, what all do I need to know and is it possible to do so with just the 302 stock lifters and dog bones and spider, I know I would have to tap the holes for the spider but will I be able to clear everything with that cam and the lifters in the 351

Your 351 block doesn't have the raised bosses for the spider hold down bolts and the valley floor isn't that thick without them. Complicating this further the holes are right over two of the cam bearings so the bolts cannot protrude into the block, so this isn't as simple as it may seem.
