Power was pretty flat between 34-36 degrees, but absolute best power was at 36. Because they were using my billet 2 wire, it was locked out. I may see the torque come up below 4000 rpm when I put...

What's Everyone Using for Engine Mount Shims?

Title is basically it. What is everyone using to shim their engines?

Thanks!



Compression came out to right at 10.3:1. We were shooting for closer to 10.5:1, but without going to a 4.25' stroke and only over-boring another 10 thousandths, I just had too much...

Yeah, he was close, although it did make above his high side estimate. He said 550-570 initially.

This is a really good point. Modern OEM vehicles also almost exclusively have dummy type gauges that soften the heat cycles as well. Oem's run cars around 200 degrees for stuff like the LS engines....

These cars are horribly undersprung as they were designed. Shocks that lack much in the way of rebound valving don't help that much.

Based on what you're saying here, I would probably recommend a...
