I posted this thought on the "other" forum and got mostly affirmative results. I have an lt4, stock. I have read about putting 1.7 rollers to add lift. From everything I have found, this should be a pretty simple deal. I know I will need new studs and guide plates. As I understand, my stock springs, pushrods and lifters should be okay to handle it. What I do not know is where to find them. The only thing I can find are for lsx's or big blocks. Will lsx rollers work on an lt4?

Nathan Plemons did this upgrade... I don't remember what brand he used, tho...

I thought the brand was Scorpion.

IIRC he tried to go even further and found a set of 1.8's and did not have any gain over the 1.7

Where are Nathan and Glock?

I think he used Scorpions. I'd advise a spring upgrade though. I just don't like using worn stock springs to do more than they were designed for.

yes, Scorpion.

I remember the 1.8 experiment... it actually lost some performance, IIRC.

I can drop him an email... if is address isn't the school one he was using. Nathan has found himself a sweet looking young lady... so he vanished.

Here is a little from his site, I believe the place to get them was
