I don't recommend following my lead on this one. I have twice had grinding bits embedded in my eyes. Once was while wearing goggles with vents. The bits came thru the small holes. the Second time was while wearing a full face mask. the bits just bounced around.... Not that I recommend wearing nothing...... Just sayin' nothing is perfect.
Chuck, thanks for the input...and Ouch! That's another area where I need to be more careful.
Working on getting more ally paneling done. Next up is the scuttle floor. But before cutting up more aluminum sheet, the placement of several components that will mount under the long scuttle cover needed to be figured out. The fat inlet tube to the throttle body (including the MAF sensor and air filter) had already claimed a big chunk of that real estate. The master cylinder reservoirs also needed scuttle floor space as the footwell firewall is too small and/or too close to the headers to mount the reservoirs on either the master cylinders or the firewall. The chassis fuse box needed its own scuttle footprint. And the engine harness required real estate to mount both its fuse box and the ECU.
Where to mount the ECU led to the question of where the excess engine harness was going to coil up (aka the snakepit.) Seems GM was generous in providing engine harness length and had their own approach to which wires they grouped together. So the harness layout and snakepit location both had to be resolved before proceeding with the scuttle floor.
The factory crate-engine harness was stripped of its bulky ribbed split-plastic covering and the grouped wires were separated as much as possible. The objective was to create a “home run” for each connector back to a central junction point on the harness. It took quite a while to unravel GM’s handiwork and I had to “stretch” two ground wires and the 12v wire between the O2 sensors to get all the connectors on home runs. No signal wires had to be modified though.

The picture shows some of the major wire bundles re-covered in a softer, braided harness wrap. I’ll regroup and re-cover the smaller branches with the same kind of wrap after the revised harness is fitted up to the engine. Any excess length in individual “home runs” will be coiled up and stored in the snakepit. Hopefully, none will be too short, ‘cause another objective with this harness is to not stretch any signal wires or re-pin any connectors. Been there, failed miserably at that.
It now looks like the snake pit will reside in a basket hanging above the tranny. The basket should provide storage for the excess harness, a central feed point for all the homeruns and not take up any scuttle floor space. We’ll see. Still have to find the right place for the battery.
