Which will get to the end of 1/4 the quickest

Why not build both engines and take 'em to the track and post the results. Your ride can be our test car. Hehehehehe!
I have both engines, If you have or know someone that has the tools so I can do the valvejob on the x-heads I'll put it together. I'll also need a gasket kit.
I'll also need to rebuild the small block 727.
The 440 is together and in the car.
