Roller valvetrain

[87TIGN]

How much HP does a full roller valvetrain set realistically free up? Do the 87 motors need a bunch of machineing to get them to fit and work properly or is it a drop in thing. I am looking at the Revolution X set at full throttle speed and I am thinking of buying the additional roller rockers. Any one know anything about this set or have it in their car and like it?

well, I don't know about the full throttle kit, but I have a 206/206 Comp billet roller and valve springs, SpeedPro roller lifters, 1.55 T&D roller rockers...I love the setup, plus you get to run cool tall valve covers. My only complaint, is some valvetrain noise due to the rockers, but it revs quicker than the old motor....we'll see what happens at the track!

where did you get them from?

These actually came from Rodger Davis' 9 sec. TB powered Geo Metro...but have about 200 miles on them. I bought a new set of heads and they came with new springs, so I used those instead of these.
