ok i got a 1975 350 and i wont to make it a roller do i have to do any thing to the block or can i just put the roller cam and lifters in it

 

you need a retro fit roller cam and lifters

 

like he said...there arent that many parts of a motor that make it a rollor motor....

for you its just roller cam and lifters.

 

you also need the roller lifter hold down bracket to keep them from spinng. flat tappet lifters are designed to rotate while in ioeration but the rollers are not, they need to be held in place so they dont go sideways on the cam lobes.

the bracket is usually bolted into the valley under the intake manifold. youd have to modify that to gget it to work.

 

thats for factory roller

 

yeah, for retrofit, you use link-bar lifters

 

learn something new all the time
