whats the benifit of running a 4.250 crank, 7.1" rod on a street engine?
thats pin must be so far up the piston I can't see it lasting 5k on a street engine.
or am I wrong?




The compression height with a 7.1 rod & a 4.25 stroke is still 1.48 Plenty of street motors are considerably shorter... Obviously the shorter piston is considerably lighter... AndyF does seem to favor the 6.8 rod combo...
