How Much Power Can You Gain WITHOUT Changing Camshaft or Cylinder Heads? (Expo 2024 - Episode 39)

How much power can you gain without changing camshafts or cylinder heads?
Lake Speed Jr answers that question with the 20-year-old Ford C3 engine from his dad’s garage that we’ve been working on throughout Expo 2024 (see episodes 1, 13, and 19).
After fixing some scuffed pistons (and replacing 3), and giving the block a new hone at Straub Technologies, Lake took the engine down to PME Engines in Moorseville, NC. There they re-assembled the engine with the original valvetrain -- same heads, cranks, rods, cams, rockers & springs, etc. - and ran it on the dyno to see what it would do.
Then, leaving everything else alone, they swapped the carburetor and fuel and ran it again to see what happens.
The results were surprising - and definitely worth remembering if you’re looking for easy ways to make big power.

"But wait! There's more! For only 3 easy payments of $24.99 . . ." That's all I envision when I watch this guy. 😂

Q-16 was a big gain. Oxygenated fuel !!! I’ve run a Q-15 blend that was 1/2 Q-16 and half C-15 I think it was. Bumped my jets 3 numbers and picked up in a 175 mph dragster. The Q fuels are very popular and add considerable power

What is 'blocking and tackling' in regards to engines? I presume it has nothing to do with a block and tackle?

Good morning

[@FORCFED]

Morning 😎

[@treyrags]

Maybe I missed it but trying to figure out how much gain before the fuel and carb

[@deanbryan3034]

I think it read 770 on the gauge during the first run

[@deanbryan3034]

And they said 791 after

[@deanbryan3034]

So to recap Before the engine got hurt 736 After the machine work 770 New carb and fuel 791

[@treyrags]

@@deanbryan3034 thanks. So pistons, rings, and cylinder prep worth about 35

[@deanbryan3034]

@@treyrags yeah that's what it seems like.

[@nathanrice1796]

What kind of ignition system is it using?
