ok guys i have a lot of questions on this. i was getting ready to order myself a mild hydraulic flat tappet cam, and ran across a post where some one said that in a 1991 la 318 it has roller lifters and a roller cam???? my orginal intentions were to give my engine a little more torque and a little more power then i ran into the roller vs. flat tappet problem. can you switch roller lifters and cam for hydraulic lifter and cam? id appreciate any help/advice on this guys thanks.

 

heres the cam i was gonna buy

but im stumped on where to go from here or what to do

 

Yes your 91 came with rollers. Rollers are best for performance and less wear then flats. I say stick with rollers, call up www.Summitracing.com they can select a perfect package just for your truck and your needs.
