Yes I have, and we do.. LOL again just asking. I have been doing this stuff for twenty years now, we have a very good handle on it. But only looking at afr is just the starting point a 4 gas will tell you much more. Opens up many more doors for tuning. We have to be careful not to run them too rich as you will end up building carbon and that in the long run will led to other issues as we all know.

My Stroker LS ran the best at 13.2 under that the power fell off by a large amount. I could have run it leaner and it was making more power ( we did try several ranges,.. but in the dunes the heat from the leaner afr would ramp up my coolant temp. Different beast of course.. And yes what the engine wants is how it should be tuned, there is no "written in stone" afr range .

Nice numbers!

bustedknuckles · 03-19-2012, 09:48 PM

tire fryer for sure.

I forgot about the virtual high five! I scrolled through the posts, and shawnt was closest! Good guess man! You must spend some time on the T.C. board...! lol!

Super73 · 03-20-2012, 12:06 AM

Steve, Interesting you tune them that lean. For all the LS stuff I tune, I tend to set it about 12.8-12.9.. So to me, based on my time spent on the dyno with a bunch of LS stuff, the tune looks pretty good, the top end of the rom range might be a little rich, but not bad.. All depends on what the combo wants right?

shawnt · 03-23-2012, 07:35 AM

I just have an idea on marks ability is all. Good luck with it in the truck

The engine showed up on Wednesday just as I had expected. Have been under the weather lately, so haven't even uncrated it... Here's a couple pics though. Looks friggin awesome!

mud.man.rj · 03-30-2012, 10:27 PM

Lookin good, may have to post a video of it running after all the hype, should sound pretty mean.

69GMC910 · 03-30-2012, 10:34 PM

Oh there will be video. You can count on that!

69GMC910 · 04-22-2012, 11:57 PM

mud.man.rj · 04-23-2012, 11:04 PM

Nice stall, should kick a$$ pretty nice, your right about finding time, went to work on mine tonight but ended up pulling neighbors 94GM sterring column and rebuilding it but dark now so putting it back in tomorrow then get back to my bodywork again. Bodywork is a long road.

69GMC910 · 04-25-2012, 01:09 AM

I'll start a build thread here someday... But the story of this truck is that my Grandfather bought it new in 82.. Around 1990 it became my Grandma's truck for camping with me and my brothers. Here's a pic of it in 1997. When I bought it in 2002 it still looked like this!

69GMC910 · 04-25-2012, 08:07 PM

After seeing the OKC farm truck I kinda wish I had left it as the ALBERTA CAMPER..! Hahaha!

I hope to be able to hit Castrol in edmonton at least a couple times before the Hat... Just gotta get the darn money pit on the road...!

Well if you are willing to go all the way to the Hat, may as well bring it to Saskatoon.
