Re: 1970 C10 "RATTY" - EFI 454/4L80e, patina, SWB 2wd

The last few weeks haven't been overly exciting on updates... mainly just a LOT of degreasing, cleaning, priming, painting, then repeat over and over.









A pet peeve of mine with this engine is the oil fill tube that is upfront and center staring you in the face. My first preference was to find a '91-'95 driver side valve cover to match the design and include an oil fill cap. However, used ones in rough shape go for $70+ on ebay, so that wasn't an option. So I went with the cheaper (free) 2nd option: shorten the fill tube.





Starting to look like an engine again!



The OE vortec injectors are notorious for leaking down and flat out dieing. Mine all currently worked fine, but now was a great time to upgrade to a set of stock LS6 take-outs. I'll adjust the tune accordingly to work with these.



The current focus (see what I did there? lol) is modifying the stock engine wiring harness to be stand-alone. I'm spending the time to do it right; removing all unnecessary wires, altering routings, and making the wiring as invisible as possible.
