Ok, random thinking here. Just mapping out this fall/next years project and I'm going back and forth on the engine choice.
Yeah, it's not an f body but it's automotive so let's talk. For my 83 ramcharger. Years ago my father rebuilt it and put it on a 3/4 ton chevy frame, put 35" tires on it, and powered it with a healthy olds 455.
Well, been sitting for years and I'm finally going to revive it since I basically have a chassis I can't refuse falling into my lap.
It's going to keep a 3/4 ton axles and have a 6" lift and something between 35"-38" tires on it. Right now the chassis is coming with a 4 speed manual that I may keep, or, may sell to go auto. Not sure there yet either.

Anyhow, reason for the post. I'm torn on a motor choice. I want modern fuel injection. I've had it with carb's. I think I'm down to an 8.1 big block or a 6.0. Horsepower wise they're close but obviously stock for stock the big block beats it for torque. However, with basically a cam I know the torque peaks can match up pretty close and the ls motor wins for economy hands down.
Yes, I realize no matter what it's gonna be a hog. I'm just thinking for parts availability, ease of modding, and again longer range, the ls motor is on my list. But, I know the peaks can match up, how far apart are they across the whole curve? Does a modded 6.0 have a decent flat torque curve or are they peaky?
So yeah, long story short, I know peaks can match up close but how does the entire torque curve compare between an 8.1 and a 6.0?
And, are there even cams and such for the modern vortec big blocks?
Or should I just say screw it and go with a turbo'd 6.0 lol?
