So I'm getting ready to rebuild a 340

That is the half of it. You assumed on his behalf the ride has or may have and/or he desires something more aggressive than what we suggest. You also never stated that it was with a stroker sized engine ether when you made the suggestion.

In truth, we still do not know what he has. You can make excellent power with a smaller cam and good flowing heads. A cam of your suggest size and a daily driver with a stated desire for more torque and a hope for both torque and good HP was writen.

It is hard to make a recommendation with such limited info. So a smaller cam would be a good starting point. Suggesting a cam like you mentioned requires a bit more than a smaller cam engine would. Leaning towards and away from the description of the OP wants.

When more info ACTUALLY comes from the poster........
Read his opening post , Rob.
Read "aluminum heads" "Stroker".
You and irr3333, how many 4" stroke motors have you built? How is it you agree withh my post then rebut it? [email protected] cam in 4" motor is too small to hurt torque where you two are concerned. The cam you are going towards will have the power falling off by the time the pedal touches the floor. I agree a small cam 360 still makes respectable power, but that is not the what the op is asking about. To the real point...I answered his question meanwhile you two are steering him somewhere else he did not ask to go. It's his build, his money , his choice...and wisely he is looking toward a mild 4" stroke motor and he will not be disappointed if he stays on that path.
