wheres the torque
Hi, most of my engine knowlege lies with motorcycles and a mildly tuned engine will yield app. one lb.ft.of torque per cubic inch disp..why does my 94 460 engine put out a rated 395lb. Ft.? I tow a 7000lb. trailer and i would like a little more kick in the pants get up and go. Anybody help me out with this? Thanks

Yeah but how flat is the torque curve on a bike vs the 460?
On the cheap be would be long tube headers and then a cam swap.
Other end would be a set of heads and change the gearing.
You still won't pick up much more above 400ish and keep the powerband where you want it with out going to a stroker set up.

Volumetric efficiency drops with larger displacement engines. There is more weight to move around within the engine. Also, since there's far more surface area with the moving parts within the engine, there's more friction in a larger engine.
There are a lot more factors than just displacement when figuring out how much torque an engine puts out. Compression ratio, engine design, intake design, heads, pistons, cams, timing, ignition, smog equipment, etc, the list goes on... You can get 1,000 HP out of a 2.5 L Subaru engine with the right mods.
If you have 3.55 or 3.73 gears, a switch to 4.10 (or greater) would make a big difference in apparent torque. Switching from 3.55 to 4.10 should give you a 13.4% increase in torque at the rear wheels.
