Ok, so I know that the roller was introuduced to the 5.0 in 1985. But my question is this, what is the difference between the roller and non-roller motors? Is it just the cam, lifters, and rockers? Or is there an actual difference in the block?

 

yah i don't know either lol. whats a roller engine and a non roller one?

 

cam bearings are different thats only other thing i know

 

so it wouldnt be hard to convert a non-roller to a roller? New cam bearings, new cam and lifters with stock heads off a newer model? with an injected intake

 

the non roller motors dont have the "spider" that holds the lifters in place. To convert a non roller to a roller you need to get special lifters

 

right you get the roller lifters, and the thing that prevents the lifters from turning? are the cam bearing in fact different?

 

its quite diff, and to convert it, its pretty costly instead of like $135 for the lifter its like $600.

 

wait you cant just put roller lifters from a later model in it? if not, why not?

 

hmmm

 

the HO = roller, the non-ho = non-roller. im not sure about converting or intermixing stuff, ive always had a roller block.
