351W roller blocks are F code blocks that were made 94-96. The best place to find them is in 3/4 ton and 1 ton trucks and vans.

for a roller 351 you will olny find them in F-trucks Unless you find a 351 bronco after 92 I have never sen one that new . The panthers olny have 302"s in them they went roller in 1986 but the trucks did not until 1992

To put the roller converson kit in a older 351 is not mutch more complacated than playing with dirt . just drill 2 holes and bolt down the spider with the anchorbolt in the kit it's not hard at all .

I would not turn down a good running 351 just cause it's a flat tappoid block either
