Anyone ever built or seen a 347 motor?

    Not a stroked 305, but rather a destroked 400. Large Journal 327 crank in a 400 block. Buddy has a 69 C10 shortbed that the 327(from a vette, I suspect may be small journal) died in. So his plan is to pick up a 400 another kid has, put the 327 crank in it, 327 rods, build the top end real nice and hopefully have a good revving 347. I told him he should just run a 377 but he made the good point that he has a 327 crank. Though I have extra 350 cranks /forums/images/graemlins/crazy.gif. I know 400s have larger journal sizes but you just run bigger bearings(according to mortec) for a 377 so since a large journal 327 crank has the same main size has a 350 it should work. He wants a powerful motor that revs like crazy.

    I hadn't till tonight either. I want to build a Chevy 302, I wonder if someone makes an aftermarket crank for one. Same journal size and bore as a 350.

    With today's head technology, it makes no sense to build those short stroke motors other than for competition use where CID is limited. With the awesome flowing heads they've got now, it makes no sense not to just build a 400 which will make way more power than a destroked version of the same motor, you'll just have to shift earlier.
