Sound isn't a big deal here, I may have to pull some light loads (snowmachines~ around 2500Lbs total trailer weight)
but nothing much. It'll be 4 Wheel drive, just kuz I live in Alaska, and, like I said before, sound is low on the priorities list. OH, and it'll have a big fat nice 'n toasty heater.

Then get a smaller cam. 210-220 should be more than enough. you can go with a narrower LSA with those small durations too- like 110.

so the cam specs would be more like this?

lift@1.7:i).510"E).525"
Adv.duration:i)252*E)260*
Cam Lift:i)294"E)300"
lobe center:113*
Duration@.050:i)214"E)220"

They're similar to some blower cam specs for a ls1 on Engle's catalog...

That's much better. Lsa is a little wide for that small of duration but its pretty good.

With those small seat durations 110 LSA would work very well. The biggest reason to run a wide LSA is to minimize overlap so you don't have your intake charge leaving through your exhaust before it is compressed. That cam wil have less overlap with a 110 LSA than many stock cams- meaning it'll idle close to stock but have much more mid-range power.

this will never see anything above 5000 rpm, due to balance problems, and, even with it balanced it'll sling apart.

I want my power band starting around 1000 rpm, so everything'll be down low.

what do I need to do to the cam to get that?

That last cam on a 110 will work fine for that range. Peak tq will be aroun 4000-4500 but it'll be pretty flat from idle to redline. A nice pulling combo.
