Re: shoulda used a Ford 300...dang

Going with the topic, Crower also told me about how he had stayed up late into the night building an engine for his daughter's S2000 race car. He used a set of his titanium rods, but in his late night haste, installed a floating pin a little too tight. It seized up at about 8000 rpm, blew the piston...

Re: 21 mpg 95 f-150

You start to hit an aerodynamic wall after about 23 mpg, where you can't get much better fuel mileage because of the huge frontal area of the truck, as well as the mass you're trying to keep moving. The 300 in something like an old Datsun 280Z would probably be capable of 30 mpg, but the only way to...

Re: shoulda used a Ford 300...dang

Ouch.

Bruce Crower told me once that the pulling diesels are making 10,000+ ft/lbs of torque and run 100+ psi of boost. He also said that to keep the pistons from immediately vaporizing under such heat, they plumb big nozzles under each one, which spray motor oil at them.

The easiest way to increase your mileage would be to back out of the throttle a little to maybe 65-70 mph. :D The faster you try to push a brick through the air, the more the air is gonna push back.

I put old 16" jeep wheels and tires on my Bronco and saw a gain of about 1-2 mpg. The tires are about 31" tall, but very narrow, and run at 80 psi, so they made the ride harsher. Standard 31" truck tires will be 10.50" wide and 35 psi, which is definitely not good for extra mpg. ...

The longer the rod the longer the piston dwell at both ends of the stroke, which means better combustion with less ignition advance and more cylinder filling.

They started using hardened exhaust valve seats back when leaded fuel went away. The tetraethel lead would leave a thin film deposit on the exhaust seat when it burned, which protected the seat from heat damage. With unleaded fuel, you should install hardened seats on the exhaust side.
