intake headers and intake mani work (home port job) might see 450whp on 93. You might get to 475ish with a gt350/cj/boss intake mani and corresponding larger tb I'd save up and boost it. I frequently go 5000 feet altitude down to sea level. The 15% power "gain" I get going to sea level isn't a...

so looks like it has a 4.63 pulley and a NBH 25080670HD belt. Altitude loss is about 20%. Current calc with 7.65 crank and 4.63 blower gives me ~53000 rpm at 8k 4.0 gives me ~62750 at 8k which is roughly 15% more rippems. I know it isn't linear but that seems like an ok ball park. Shifting at...

Sounds like the easiest plan. I like.
