1964 LINCOLN RESTORATION PROJECT

Here it is, at last, proof that my modifications made a difference in the engine's output! Also, proof that advancing timing a few degrees makes all the difference in the world.

Note that the I didn't go anywhere near the safe maximum RPM of 4600+ (stock power is 320 at 4600), so I can only guess that horsepower is up big. I don't want to damage the engine by accidental over-revving, so we can only speculate about the real maximum power. I'm going to get a tachometer soon to be able to safely run the RPMs a little higher and post the peak horsepower.

Torque is up to at least 492-503 (I got different results from two runs, will do another one soon to help verify) at 2900 over a stock figure of 465 at 2600 RPM; that's a gain of 27-38 foot-pounds and 300 RPM.

Mind you, for this test I launched softly and didn't quite let my foot get to the floor. I suspect these figures would be higher if I was less careful with the machinery.

Note that horsepower rose to over 300 when I let off the throttle... and that's probably 1500 RPM before the new power peak. I project the engine now puts out at least 350 horsepower in its current state of tune.

You can see where the secondaries open up, at about 2200 RPM. That's where the torque curve flattens for a moment and then gets really steep. You can sure feel the thrust!

Now with a little more tinkering with timing and jetting, as well as opening the secondaries more fully (I have them set so they only open about 3/4 now), the engine should be good for another 10-20%% over these figures. Gosh, with a big, fat cam, the sky's the limit... Fun with tuning!
