I've got the S1X also and have been looking at the Yella Terra 1.6:1 Roller Rockers. I've got a set of 1.9:1, but after I got the cam I thought that retaining the stock rocker lift or near rocker lift would be okay on stock heads. I don't think I would go over 1.7:1. You think I should stick to the 1.6:1?

I think you should stick with the 1.6:1 on the stock heads. You will have clearance problems going to 1.7:1

Do you plan on replacing the case bearings?

Those look perfect and will be regreased.

Got the supercharger all done.

Finished porting out the inlet.


A view of the inlet. I filled in the divot.


Brand new green coupler.


I have one last thing to do, and that is to cut off those 2 bottom bolts so they sit flush.


And there she is all done. now wouldn't that look great on top of your engine?

Nicely done! Looks great Dan. What did you use to fill in the divot on the intake?

Some JB weld. I roughed up the surface with a small carbide bit and then pushed it in to place.
