ok stroker guru's, gig this one

yes dwell time is the amount of time spent at tdc and bdc,

...longer rods have more dwell at TDC which allows long rod motors to build more combustion pressure at 'high RPM', and then less wear on cylinders/skirts.

short rod let the piston move down quicker, and supposidly produce better torque at lower RPM and typically like more timing advance, hence the road race chevro crowd.

btw the 2 are different......


tdc dwell time is not the same as bdc dwell time.
