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 .

Re: 496 to be DYNO'D!
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?

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!

Re: 496 to be DYNO'D!
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.

Re: 496 to be DYNO'D!
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!

Re: 496 to be DYNO'D!
I haven't been out for about 3 years kinda took a break but hope to do some racing again this year. Was down to the Hat once before and liked the track, their LED lights not so much LOL, wasn't use to them.

Re: 496 to be DYNO'D!
Well if you are willing to go all the way to the Hat, may as well bring it to Saskatoon.
