last weekend, i was helping a friend put together a 302 for his 89 Mustang, when i decided to break out the old beam type torque wrench to see how much torque it takes to spin over a fresh shortblock- the little 302 with no heads on it took about 35 ft lbs. this is with new standard tension oil rings and that thick red assembly lube on all the bearings, so that had to add a bit of friction.
then, since i had the 355 from the Nova up on the stand, i decided to pull the plugs out and see how much force it takes to spin that over- it took a little less than 20ft lbs with the engine complete but with no spark plugs. that seemed pretty damn good to me, and helped to account for why the thing revs so damn fast. of course, it has those stupid race low tension oil rings and about 30,000 miles on it so it is nice and worn in, but it still seemed low- i can damn near spin it just by grabbing the balancer.
has anyone else checked to see what a "normal" engine takes to spin over? just one of those curiousity things.
you don't plan sincerity.
you have to make it up on the spot.
wanna hear about 20 years ago when i was too smart to know any better?
