Re: PROJECT: How would a Chevrolet dealer build a shop truck in the early 1970s?

More pics. Air cleaner base for a Corvette or Z-28 Camaro with the LT-1 350.

Several views of the carb that was driving me crazy and is now ok.
It would only start when primed and wouldn't idle very well and would not restart unless primed.
It turned out it was a bit of green sludge from not running it often enough.
Accelerator pump circuit (and probably idle circuit) clogged with a minty green sludge.
I think the ethanol gas and brass float were not playing nice together when run only once every six months.

As a side note, it was kind of fun fiddling with the Holley (Street Avenger 770, very similar to the LT-1 spec 4150, 780cfm).

The new fan shroud that makes cooling more efficient and protects careless hands and fingers.

Installed a new/rebuilt Delco alternator with internal regulator. New alternator was hooked up using a handy YouTube video without much wiring other than swapping my old terminals into the new connector and plugging a couple of jumpers unto the old connector for the external regulator. It charges at 13.7v.

Here's the video I followed for the alternator conversion:

(It was surprisingly easy.)

Things keep getting better.

It charges and I'm shocked at how well it starts and idles.
