318 build suggestions?
Top one 388-400 hp from 5,500-6,500 rpm that's a pretty wide peak hp and torque pretty flat from 3,500-5,500 rpm 371-382 tq.
The others aren't looking too bad either, look like pretty good power curves to me and all that was mentioned was a peak 400 hp goal, and all I said was the recipe seems fairly consistent be it a 318 or 340/360.
Magnum headed 318, pretty similar to the 380hp crate 5.9l.
