RMS 427 Hyd Roller results! Car Specs:
99 Hugger Orange SS 6m
C5R Block
Callies 4.000 Crank
Lunati Pro Billet Rods
Diamond Pistons 4.125 Diameter
11:1 Compression
RMS Stage 3 6.0L Heads
Comp Cam 244/244 .615/.615 112LSA
LS6 intake
RMS ported TB
TSP Lid
RMS Tuning
Jett Hot Headers
Cutout w/Hooker catback
Moser 12 Bolt w/3.73 Gears
We didn't get finished since the GM slave blew out on the last run. But the last numbers running kind of lean.
503rwhp/509rwtq
I'll post the graph later today but it peaks at 5900rpms and makes some nice low end torque.

A big CONGRATS to an AWESOME ENGINE and great numbers. That BEAST is very similar to the MTI 427 C5R motor lurking beneath the hood of my 98 C5 Roadster. Your gonna love that TORQUE throughout the entire RPM band. My BEAST with the 4.00 lunati crank makes 100 more rwhp between 3500 and 4500 rpms vs. my old 427 iron motor with 4.125 crank!

Well, we should be doing a little more tuning later in the week on this car. I think there is still quite a few more horses lurking in the tuning. Look for a post later in the week for an auto 427ci build up we have done that is a mirror of this motor.

Yeah Mark I hope to be there next week to Dyno mine, I still want a few more miles on it before we go WOT, but this thing is a beast the Torque is amazing... at any time I can roll on the throttle and break the tires at almost any speed and I have not even been close to WOT yet 
The only problem I have had is all the attention I get around town with the cats out this thing sounds awesome and the lope is not bad enough to kill it but does a great job at turning heads at every light. Cannot wait to see the numbers we put down with the auto.

And all the other goodies that make up a Fbody to fear
