Engine specs.

Can anyone tell me the horsepower and torque ratings for the Inline 6 and the 302 V8. Also which has more low end grunt. My personal vehicle is an 87' F-150 4x2 Manual, 183,000 miles and still running strong. I have another question as well. I've heard a lot of good reports about K&N air filters. Is this filter worth the extra cash, can you really feel any difference. Thanks for the input.

The EFI 300 was 150hp@3400 rpm horsepower and 260lb/ft@2000 rpm. I'm not totally sure on the early EFI 302's ratings. The I6 definately has more low end then the 302 and is a very strong and durable motor.

you said you were condsidering a K&N air filter to increase horsepower, i recently got one as a present and i would say get one, but dont expect too much of an increase, it helps even everything out, helps acceleration/deceleration, and helps shift better too, but its nothing like if you were to place a performance intake or headers to it.

I have an 87 F-150 300/6 manual trans, (which just died, the front bearing went out), 197,000 miles. I love this truck. The motor is still going strong! Anyway, I put the K&N filter in last year and so far so good. I'm not sure how much improvement the filter made because I changed over to Mobil 1 10W30 at the same time. Which ever one or the combination of both, I am impressed!! The truck runs smoother, lower operating temps, etc. Like I said not sure which one or the combination that improved the performance but it is well worth the money as far as I'm concerned to use the K&N and change over to Mobil 1 oil.

I've thought about changing my oil to synthetic, but have heard so many different stories about putting synthetic in a high mileage motor I've been leery of doing it. I have 110,000 on my 85 4.9L and she's strong as train smoke. I do have some leaks, mainly near the back of the engine, and wonder what a synthetic oil would do in an already leaking engine. Have you noticed any leaks, or any change in pre-existing leaks?
Thanks for the input.

The best way to think of synthetic versus regular oil is as shapes. Think of regular oil as varying sizes of spheres, pyramids, cubes, cones, and cylinders. Think of synthetic oil as small, evenly sized spheres. That is to say that synthetic oil can fit into tighter and smaller spaces than regular oil and causes less friction because it is more uniform("spheres" that can easily slide over each other). If you change an old engine over to synthetic oil you can probably expect to see a lot more leaks because the synthetic will get into places that the regular oil never could.
