Re: 85 C10 LT/6L80 Frame off build

Love the setup(s) and the truck is clean as hell. excellent work. I found a 6.2 and 2wd 6l80e, with harness, accessories, and driveshaft, out of a 2012 silverado with 116k miles for 5 grand. Been thinking all day about changing out my cammed L33 and 4l65.
I read some people saying the 6l80 isn't as strong as a 4l80 and can't hold much more than 400hp. Any concerns with yours? or are you staying relatively mild with the LT?

a 6l80 will handle much more than 400hp 6l80 is super sensitive to the tune so once someone goes to tuning on them they go to crap. there are lots of people making north of 500rwhp with them. no issues for me, mine will be 420 or so hp so it will last forever

Re: 85 C10 LT/6L80 Frame off build

Rear-end build time, for years I've been using Richmond gears with no issues. I like how they have the pinion depth on the pinion head, makes set up much easier. I will also be using their Richmond Excel axles and set-up kit to freshen up the 30 year old 12-bolt.


Richmond 3.42 gears 49-0070-1

Richmond set up kit 83-1018-1

Richmond Excel axles 92-25192

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
