Datsun 4 cylinder engine, perhaps 2200cc, maybe
8 spark plugs, 2 distributors, 2 coils, double the fun, double the trouble.
Single Overhead Cam, double roller cam chain. No belt on this baby.
4:56 Ratio rear end
~135 HP @ 5600 rpm
*TIP*
Adjust the valves a bit on the tight side, except the intake valves put them .0005 on the loose side.
Bump the timing to 12 BTDC
Cut the snorkel off the breather, leave the hot air intake just cut off the small end.
When you blow the head gasket, have em shave .020 off the head & get the thinnest head gasket you can find.
Run 92 octane fuel at 5,000 ft altitude or less, 89 octane in the high altitudes.
Clean the carb with some Chemtool B-12 by Berryman, pour it in the tank per directions. Then change fuel filter.
Adjust the clutch to release just off the floor about 3.5"
Now, you got yourself a Ranger eater
211,000 miles has just about gotten the rings broken in against the block.
Those engines in that era of P/U were unholy powerful, they also will bolt up to the older Datsun 510 series cars, and promptly smoke the rear tires up
Now, what kind of truck is that again, don't think I've ever seen one like it.
