Wrong on the 305 hp and torque ratings...unless you talking about a 305A Net hp. lol The 305E was rated a 165 hp and 280 torque. And true...the throttle body 350 my make more torque but at What RPM? I hit peak torque at 1600 and your 350 is lucky to have maybe half its torque at that much. I can lug mine up a hill in 4th gear and she'll hold speed because I have torque where as with a 350 since torque is gonna peak around 3000 you'd have to down shift to hold speed or else its gonna bog down and die because your loosing torque as you lower RPM whereas since I peak torque at 1600 and if I was driving 55 @ 2500 as the engine lowers in rpm from the stress it is actually gaining torque again causing it to keep going. That's where I'm coming from. Unless your 350 is a very low duration low rpm machine it just won't lug like a 305. And I know guys who will agree with me. But I don't wanna bog my thread with arguments. This is a build thread and not a debate thread.
