5.8 roller?
When did ford switch to the roller cam setup for the 5.8? I was told it was 95 or 96, but I checked a table that has the stock power ratings and it jumped up in 93 and stayed the same until they were discontinued.

The roller setup started in 94, or even late 93 in some but not all applications. All 94-up engines are "roller compatible", that is even if they have a flat tappet cam, the block is designed to accept stock roller lifters and cam.
The sure way to determine if a block is roller compatible is to find the "F4TE" casting number prefix on the cylinder block. It is above the starter motor, visible from below the block (the starter may need to be removed to see it though).

Yes, but the 5.8's didn't get a roller cam with the F4TE block until 96/97. Those (5.8) blocks will accept roller lifters, spider and dog bones from any factory rollerized 5.0 of that era. Just need to change the pushrods and the distributor gear to a steel piece.

The switch to mass-air didn't occur with the switch to the roller cam. I've seen F4TE roller cammed 5.0's (same cam used with the roller 351) that still had Speed Density EFI. Easiest way to ID a roller is pull a pushrod and measure it. roller 5.0 rods are 6.25" (give or take a few thousandths) 351's would be 7.55"

How much would it cost to change a 351w from hydrualic to roller? and would it be worth it? I'm looking to get real good power for racing and pulling against people that think chevys or dodges are the best, yet get no worse than 12mpg if possible.

Does it make a difference whether it is f-1,2or350? What would I have to do to it to make atleast 300hp and 325tq, preferably more but my budget isn't all that big($1000 is the most I've got, maybe not even that much, it depends on how much the truck costs.)
