Harry Mann 68 L78 / L88 Camaro

While I'm waiting for a customer to pick their car up, I thought I'd get going on a little L88 maintenance.

The valve lash has HARDLY moved. Int .019 cold, Exh .021 cold. I have my thoughts about the plugs, anyone else care to chime in?

----Switch to Autolite plugs. I used them in Red Alert (780hp) and hardly ever had to change them....Bill S

Looks like it needs an Italian tune-up Tim!!

[Crush]

Let me borrow it for a few weeks and I’ll figure it out ��

Tim, they're smoked huh! We're running NGK's in all big block non show cars. Impressive difference...

I started using NGK in my L78. Will never go back to another brand.

Despite the lead stains / deposits, I thought they were a little lean.

My engine builder swears by the NGK's. He kinda shakes his head on a restoration engine and I install AC's

I finally installed the ZL1 fuel pump yesterday. I must admit, Chuck got my attention when he burned down his 496. Not digging the fitment of the fuel line as it's right next to the lower hose. I'm thinking I need to research some period fuel line configurations. Also giving credit to Chuck, I feel inspired to add a nice matching Sun blue line fuel pressure gauge.

You guys have any neat pics or ideas? I've see more than a few Motion installs that have nothing more that rubber line after the pump. That is not an option for me.

Tim, when I built my Chevelle race car in 1973 I mounted the fuel pressure gauge in a 2" chrome tail pipe extension mounted on the cowl vent panel. (Center of this lousy half century old image). No fuel line inside the car

Here's how the factory configured it.

The ZL1 pump looks so good! That would be very appropriate for my build as well. I like what William posted. The 90* fitting with the pump clocked a little may work in your application. I made my own line, which still took me three tries with the engine out of the car. As you can see, mine snakes around the lower radiator hose

I have seen photos of motion cars that used the factory hard line from the fuel pump connected to a generic chromed holley dual feed line with a rubber hose. I used a copper oil pressure line for my fuel pressure gauge because I felt it looked the period.

FWIW I believe NHRA does allow a mechanical fuel pressure gauge in the cabin if it is a steel braided hose, I've seen drag cars this way
