I was wondering if anyone can tell me the stock hp and torque numbers on the 70's 318, 360, 440? Or where I can find these. I currently have a 318 and a 360. The 318 is in my tow vehicle and would also like some suggestion on power mods for this or if I should just switch to the 360 or 440. The truck has a 727, D60's with 4.10. Thanks
