5.9 Magnum Torque motor build?

real close rumble
agree with leaving it alone till he gets a baseline - don't jump till you know which way and how high
The one of the other 318 HR's is slightly bigger than the 360 and should be a freebe from someone who has done a cam change
I do know that the RT cam or the Sausage regrind would cost him low end and they are not that much biggger- not worth it IMHO but let's see the baseline
Was not suggesting he build his own but figure out what to look for I'm thinking of 1 5/8 40 + inches long with a 2 1/2 collector but no idea if would be available for his chassis
BTW
here's a PM I got from over at FBBO

Hi Wyrmrider!

The motor's been dyno-tuned. Here's the dyno chart. I'm pretty happy with the results. 417 peak TQ at 3700 RPM. That's pretty good for a motor with a fairly stock idle, good vacuum, and assuming longevity. What surprised me was the extent of the power band: 90% of peak TQ from the bottom of the chart (2800) to 5100. 363 HP at 5000. 90% of peak HP from 4200 to the top of the chart (5200). The HP peak had a bit of a nice mini-band, too. I bet the thing would have had 350 through 5500 or so. The tires will not be happy about this. By the way, my name is Maurizio.
