I have heard that this crank swap is possible... just wondered if anyone has put the 400 crank into a 351W, and the details if they did?

 

[updated:LAST EDITED ON 28-Jan-02 AT 02:20 AM (EST)]this doesn't exactly answer your question, but i checked around houston trying to find a place that would do the machine work. i had to do a lot of looking just to find a place that could/would do it. it was about $250 to get the counterweights cut down just so the crank would fit in the block. another $250 for .17" offset grind to stroke it (optional). aside from that there is some work needed so the timing gear & balancer will go on - i'd guess about $40 for that. and of course after getting the counterweights cut down it'll need expensive heavy-metal balancing. i have no idea how much that costs.

i decided to go with the 351m/400 block, because of cost of the crank mods and the fact that you can use longer rods, and because i want to use cleveland heads...

i've seem 3.85" and 4.00" stroker cranks made for the 351W on ebay that were about $500, so it looks to me like if you want to use the 351W block, then one of those would be about the same price and MUCH easier!

 

Yes they do fit and there's a guy down in Texas that does it too.
Paul's Crank shop has done one or two of them he has a web site too ..
