the 4.3 is a torque MONSTER. it makes the 4.0 OHV and SOHC look like soft little baby kittens. it made up to 190 HP and an ungodly 245ft/lbs of torque. by contrast, the 4.0 OHV makes a meensy 160HP with 220ft/lbs. even the SOHC is only rated at 238ft/lbs...but with more HP at 207.
on top of that, most of the RWD s-10 trims are lighter than most ranger RWD trims. i also have no idea what chevys speed limiter is set at.
but, those are all flywheel HP figures. your typical RWD drive trane will soak up roughly 15% of your flywheel HP (more for an auto). so even a SOHC ranger is only putting down 175HP at the wheels. a 2900lb ranger needs more than 180WHP to hit 93MPH on the 1/4 mile.
a 3.0 ranger is seeing about 125HP at the rear wheels (depending on year). thats good for about 82 MPH trap speed.
1/4 mile ET's, trap speeds, weight, and HP are quite accurately calculated from one another...so all these number are very close.
