A 6mm (1/4") stroker crank with the 1250 piston/sleeve setup will give you a 1350 that is very dependable with great low end torque. Fairly easy to build, requiring just a bit of internal grinding to clearance the crank, add in good cams and valve springs, injectors, larger throttle body, a good tune, and it is capable of mid 10 sec. runs or better at the drag strip. Loads of fun as a daily driver and they hold together very well.
It's not how fast you go, it's how fast you get there!
