I am looking into swapping a 351W into my fox. My question is roller 351's are hard to find here in Canada. Which is better to use as far as parts availability and power making a roller or non roller? Non roller 351W are a dime a dozen here. And I dont want to buy are non roller and convert it.

I have a '95 5.8 roller block in my '93 COBRA, I found in a salvage yard out of a F-350. However, from what I understand the older blocks contain more nickel from factory and the rollers are the weaker ones. It may cost a little more but you could always get the roller lifters with the link bars to install a roller cam. I think, unless some machine work is required on the block to accept the roller cam.

mine is a non roller and there are several cams that work well with efi if thats what you want. i wish i'd went with a 331 and a trick flow top end kit on hind site though...makes good power but it's so much easier when you have a regular 302 block and you can make all the same hp.
