Roller 351W question

[Donstang86]

When were the years a roller cammed 351W was offered in Ford trucks? I believe 1995 time frame but I'm not sure.
Also would anyone remember the year the Ford Explorer has GT40 heads installed and not GT40P heads?

No one remember when the roller 351s were offered?

Roller 351's started in 94/95

gt40 heads were used until mid 97 year, and from then on the gt40p heads were on the 5.0 explorer/mountaineers

1998 was the first year for the gt40p's.

Any 351w can be made into a roller block. All of them easily accept roller cams, its the lifters that are different. You could have any pre '94 block drilled and tapped to accept the "spider" bracket to hold regular roller lifters(which the >'94 blocks already have), or purchase retrofit roller linked lifters from Crane or similar company. The retro lifters are about $400 though.

the link bar lifters are deff your easiest approach, tapping the valley and finding the correct lifters proves to be a task as i have done it before and everytime i try and find the correct part number it seems to have changed a little and i order the parts and the lifters are to short or something stupid like that ...
