Aluminum L head install, Link to G503 thread

Sorry if this is an Repost, but check out the before and after dyno test of L head high compression head installation. 25% increase in torque!? Wow. I need one of these for my MB. STAT!

And I love the photo/video of a GPW on a chassis dyno! It's just SO incongruous, it's hilarious.

 

Thats really a pretty impressive gain, can you imagine the driveability and power gains with that head a fuel injection setup and header.

 

I'd guess the higher compression ratio is made practical by the quality of fuel we use today?

I recall reading that the octane of early fuels was really low ... and this engine had its origins in the 30s.

Interesting. I don't remember seeing or handling those heads when I worked for Brian... but the L134 was old stuff even then.

 

So are there still heads out there available?

 

yea, that's cool. And like Mike said, through on some FI, elec. ignition and a header. Curious what you would end up with.
