[QUOTE="tt335ci03cobra, post: 16272268, member: 68944"] Just finishing the work day and say you posted a link, Very nice, it’s funny we both made 1208whp, I laughed when I saw that. You made it around 6200rpm if I can marry the speed to the rpm well. My dyno pulls I’ve loaded in this thread are to 7k rpm, we’ve taken my combo to 8000rpm and power stays level/falls 10-20whp. I have a 3350lbs car and 315’s out back so my entire build is around making whp from 6000-8500rpm irs and 6spd so we strayed from torque intentionally. I previously had a 5.4 with 57’s then 61’s. It made too much torque and kept blowing up the t56 and sheering shafts. Intentionally I wanted a power band like a built rb26 r34 skyline motor. 8500rpm peak, with great power from 6-8k, and decent power above 4, quick spool from 2500 up. I also have 3.73 gears and can stretch 1st to about 65mph north of 8k. You have a solid 5.8 (edit 5.4)* build but I’d caution revving it past 6500. Even 6000 is plenty. Just let the torque carry you to 6k and shift, there’s a lot going on regardless of the rotating assembly’s strength. I would rev my 5.4 build to 6500-7000rpm and it blew apart. Many 4.165” strokes regardless of the build fall apart with 7k rpm. I’m on Firefox for iPhone and it doesn’t open a new window when you try a link so I’m going to edit this with more about your build in just a big. Gimme an hour or so. [/QUOTE]
