The purpose of creating the charts was to determine how far I want to go with my 261 build for maximum street/freeway performance.
Looks like boring the cylinders, raising compression ratio and a mild cam upgrade is where street upgrades are maxed.
An HEI ignition would be another upgrade.
All upgrades show biggest gains per 1000rpm between the 2500-3500 range.
Gains level off after that with the street upgrades.
Perfect - that's exactly the range I will drive the most.
McGurks article and the dyno numbers are truly a great aid and guide in rodding the 235/261 engines.
The graphs give a helpful visual image of the numbers.
