Is my 340 stroked

well...stoke your 340 to 416, put in a high lift short duration cam and .410 gears! It'll be
like driving on ice!
I have never understood this. You described my car almost exactly except it is on a 6” tire. Engine makes a ton of torque? Don’t push so hard on the “go” pedal. If you are driving it in the rain all the time Ok. A “fun” car? Build it for all the power you can afford comfortably.
