Field notes

The site organizes LS/LT truck work into technical guides, build records, tuning workflows, calculators, and searchable garage discussions. Its calculators address RPM-to-MPH, tire diameter, effective gearing, and a power estimate, while the tuning material names RPM, converter slip, spark, EQ, and knock as channels to inspect. A featured Silverado record includes an LY6 6.0, 6L80E, cam specifications, 243 heads, and 4.10 gearing. Community participation is presented as account-gated.
