you just have to use a couple of special items.

you have to get a custom small base circle cam
and you have to use the expensive retro fit lifters with linked cross bar.

other than that good to go.

and yeah roller blocks are hard to find. I had to pay an extra $300 for my short block
for them to go out and find a roller cam block, but my off the shelf cam selection was
pretty good since I could use any 302 based cam I wanted, granted it had a "stroker" profile.

BE CAREFULL, do NOT use a standard 302 cam profile in a 351W, get a "stroker" cam made
for the bigger displacement and stroke ( has to do with duration and lobe sep. ect )


Roller blocks came in 95-98 F-250's for the most part I think, they only made that style
block for about 4-5 years.
