402 L92/L76 is on the road I got the car back this morning. Here are the build specs:
SDPC LS2 402 2cc pistons
L92 heads - 12:1 SCR
L76 Intake
Comp 921's
Bret Bauer custom cam spec'd for my setup
RAM Dual disc clutch and Aluminum Flywheel
American Racing 1 7/8 headers
42 lb Green Top injectors
Revised Cadillac Racing lifters - Good for 8k RPM
Trend .110 Pushrods.
etc
etc
Assembly/Installation and SD tune by Phil Thomas
"MAF, We don't need no stinkin MAF"
The car runs really strong. It's deceptively fast. It doesn't have the cammy feeling the 346 did. It just builds speed quickly from 2k RPM up. The power is VERY linear. It makes a ton of torque.
Much less valve noise than the 346. I think that may be due to the Caddy Racing lifters. Got a lift down to pick it up from a well known C5 forum member with LT's and bolt ons. I'm not naming names here to protect the slow. On the way home we found a closed course and tried a side by side roll on from 2k in 5th gear. I pulled him by 10 car lengths to 100. He said he felt like he was driving a Toyota. Did one hard run - still on the closed course - in 3rd. It hit the 6600 RPM rev limiter almost immediately. Got to bump that up a little.
The tight LSA cam sounds nasty at idle.
The car does not smoke at all and is a blast to drive.
The RAM Dual Disk clutch requires little pressure. It may be softer than stock. No chatter and it sticks hard. Going to take a little getting used to.
The overall effect is great. You can definitely feel the benefits of the larger engine even with the cam I'm running it's going to be a great "grocery getter"
Thanks Phil, Bret, Brian, Thomas and about 10 other people for knowledgable input into this build.

No dyno numbers. It's got an SD tune on it that's probably 95% done. I'm going to break in the engine and clutch and we'll finish the tune.
I told Bret it runs like a huge electric motor. Mash the gas and it just goes. Incredibly smooth power delivery. My last engine was around 460 RWHP. This is sooo much stronger it's not funny. As I said, it just builds speed form 2k up to rev limiter...OOOPS.

Glad to hear you finally got it going.
I've been visiting this site for the last couple weeks to see your progress. I was a little discouraged when I couldn't find the original thread. Hope to see/hear a video soon.
Congrats.

What did your DCR come out to be with that SCR?

I'll have a video up later tonight or tomorrow. This thing sounds SICK at idle.
