My 273 Experiment

They are a little more $$$ but built right it will suprise you! thease motors like short duraiton tall lift cams & higher compression really helps too. id build the 273 man. X4 on running the 273 steel crank. Mine is really close to stock specs other than pertronix & E-4 cam with 1.6raito rockers & it kept right bside a sweet looken 70 road runner with a close to stoch 383 hp until 115mph then wy wife yelled @ me to lift. nevr lost an inch. that guy was impressed "ive got 110 cubic inches on you & you didnt lose an inch" that aint rite.
