you will not loose torque, but in general most engine mods will push your torque curve up higher, so you will have a little less torque down low. No matter what you do to the 300 it will be a torque monster.

if you could find a way to move the torque it makes up to about 5000rpm.... that would be very good. But i think the internals are a bit too big and clunky to be doing that.

The internals of the 300 will take 5000 rpm but the problem is the engine does not breath.
If the 300 had a cross flow head then it would rev .
You have to remember that this is a low(engine rpm) speed truck engine -but it will open up with some minor porting and a better intake and exhaust system

ah... i'd never trust a 300 above 5000.
I'll agree that it doesn't flow for crap though!

from the Edelbrock Catalog:
"FORMULA FOR HP AND TORQUE"
HP=TORQUE (times) RPM (divided by) 5252
TORQUE = HP (times) 5252 divided by RPM
