Also, I know you have to modify the valve covers for them to fit, is there anything else NECESSARY for them to be installed? In 3800s you can just bolt them in and forget about it basically. I assume it's the same way in an LT1?
You could try a Google search for the company who sells them or, use the Search feature on the CorvetteForum (Forums.CorvetteForum.com) because I know there was at least one guy who bought a set.
If memory serves, he wasn't happy with them though; can't recall the specifics.
I did a quick search for you and best I found were 1.65s.
Another thought is the aggressive ramps that are on high performance hydraulic roller camshafts. I've read where going with 1.7s on cams with aggressive ramps causes valve float as the RPMs climb. Seems the 1.7s causes the lifters to be unable to follow the cam's lobes.
Just FYI Scott, stock the LT1's are 1.5. 1.6 is the common upgrade ratio. 1.7s are available but hard to find.
Any of our sponsors, such as CSSI, can hook you up with a set of full roller 1.6s. The valve cover mods are minor, and yes you need to upgrade your valvesprings.
Yeah, but his comment about the 3800s makes me think he thinks 1.7s are the standard upgrade....the, just like the LS1's are 1.7 from the factory and the upgrade is to 1.8s.
I know 1.7s aren't common. I know 1.6s are. The guy who owned the motor I bought had 1.7 rockers and his engine seemed to LOVE it. So I was looking for some.
yea he is right get some headers first, the stock exhaust is rather restrictive and you wouldnt see as big of gains with more lift, honestly I think RR's should one of the last bolt on mods, I know I did alot of stuff first before I started buying stuff for my RR swap
Get the Scorpion 1.7s NSA rockers. You need some GM guideplates and maybe a couple other things, I don't remember. As far as the valve cover clearancing, just get the valve covers I gave to Kevin that are already done.
I just received a response from an EBay seller of 1.6 Scorpion SA roller rockers and he wrote that they will clear the black valve covers - like the ones on my 96 LT1 Vette - but not the magnesium covers.
This is an older thread, you may not receive a response, and could be reviving an old thread. Please consider creating a new thread.
