not to butt in on u guys or anything but horsepower looks good on paper but u drive on torque. torque is derived from displacment. a 500 horsepower or better four banger is only gonna make power at really high rpms i.e. 8000 or more power like that is kinda useless to me on a trail, find a few more inches of displacement rather than spend 15000 to 20000 on a 2. whatever. Do you know what kind of power you can make with 15 grand in a small block? Thats the kinda power that will send a d-60 off with its tail between its legs ya know what i mean
how about bored .060 over and stroked, fully balanced , deburred,
