Two of those terminals are for the oil pressure switch that provides the parallel path to energize the fuel pump. The third wire is for the gauge sender and grounds through the housing.

Thanks for the info. I'm still learning this stuff. So why do you say aluminum gives a poor ground?

Just finished fitting the exhaust. Now on to wrapping it.

That looks great!

What's the piece of cardboard for? Is it to simulate the frame rail, so that you can build things on the engine without having to put it in the car to check for interference with the rail?

On an unrelated note, they really don't make intake manifolds nice-looking nowadays... my friend's Subaru looks like that with the ribbing to keep the manifold from imploding.

Bravo!!! Nice job!!

The cardboard is the start of a pattern for shift cable bracket. (Next project)

No, the intake manifolds don't look to great, but making it out of plastic and redesigning the heads saved 20 pounds. The LFX weighs about the same as the stock 2.8.

Was there a plastic manifold for any LLT application?

One can build headers for an LLT, but not for an LFX.

Will, no plastic intakes for any LLT's, they were introduced on the LFX's and on with the LGX. Only exceptions were the LF3 and LF4 with the integrated IC's

Daryl,

FieroGuru makes a very nice shift bracket and cables for the F40 setup.. I have a set and have test fit the bracket only thus far.

also

The camaro LFX intake manifold, although still plastic and ribbed, should be able to be reversed and utilized and V8Roadsters makes a nice carbon fiber cover for it..
