Pete, this is the same engine that's been in my car since the late '80s. It's a bowtie block with a 6223 crank. A few years ago I swapped the LS6 rods and TRWs for a set of Molnar rods and Diamond pistons. It's a solid flat tappet cam with around .605 lift. The heads are 077 aluminum. If you look close you can see the snowflake above the number 2 exhaust port. I have been running a Holley strip dominator with a 850, but decided to go for a different look this year. I don't expect it to make any more power this way, but I've always wanted to look at the back of a tunnel ram while driving down the road.
I'm using a new AutoGear N24 transmission this year, and the rear end is a 9 inch. I haven't updated this in a while, but most of it is here.
