Hey guys picked up l99/6l80e complete with ecm, maf, pedal. Going to swap it in my 77c10. So far I'm going with Tejas motor mounts, Tejas transmission cross member. For fuel system I'm already have 87 tank, 87 sender, walbro 255 pump. So far I'm gathering all the parts before I start the swap, so any input can be greatly appreciated. So far this is the list what I have now and in bold it's what I'm planning on getting. Any input from other is always welcome
Engine/trans: l99/ 6l80e
Gauges: Dakota digital vhx
Motor mounts: Tejas steelworks
Trans cross member: Tejas
Oil pan: lsa ctsv
Ecm: PSI or lone star ecm and harness

Should be a fun build! Looks like a solid parts list so far. Getting Tejas stuff you must be on the Facebook forum for LS swapped square bodies?

Awesome. I love these forums for build threads but that group is way helpful for technical questions.

Interesting that the 6l80 doesn’t have the neutral safety switch on the tranny and the tailhousing is so stubby. Guess I’ve never seen one before

If you use the Tejas Steelworks mounts and trans crossmember, it will fit without cutting.
