What do you think paul's 1979 C3 L-82 bad *** Vette puts out RWHP??
Well, she final hit the Dyno this morning.... first took her through a canyon run for about and hour and worked her hard then straight up on the Dyno...
I will post the results in a few days... after a few votes....
Below are videos, click on the for the run....
engine in a nut shell: 427 sbc, AFR 220 competition ported heads, AFR titian intake, Chris strub cam, EZ EFI 2.0 FI, 1 7/8" Kooks headers, 3" X-pipe borla exhaust, and every other whizz-bang i could think of putting in her... :-)
TKO 600 manuel transmission, McCloud twin disk clutch.
Dyno-Jet 2000

Stick or auto?
If its a stick, I'd say 450-475hp....
Auto, 400-425 unlocked.
This ^^^ is on a DJ248 dyno..

also the mini starter is giving me maxie problems?!?!?!? Time for a new one..
I still wonder what the drive train loss is?!?!?

You have the estimated drive train loss, also loses from exhaust restrictions...Lastly the parasitics from the accessories...
Drivetrain losses will vary due to the IRS components... A 12 bolt IRS is gonna eat up a lot more power then a Dana 44.
With a stick, average 3" exhaust and no mechanical fan, I'd guess-ta-mate 20% diff from crank to wheel hp. No scientific data to back it..
But I have engine dynoed mine and chasis dynoed it and I was over 30% loss with the auto/converter/heavy IRS parts.

Paul.....I think you will have a VERY expensive tire bill every month!!
I LIKE IT! Good Job!!
Now...we see what the hard numbers are....and you have blown away the expectations....Im looking for some driveability perceptions.

1}The flow numbers for the heads intake / exhaust.
2) The exact compression ratio.
3)Exact cam specs.
3) And what numbers we will be looking at whether STP correction factor or raw data.
These are questions anyone needs for a good educated estimate
4) One last thing,,,,,,what RWHP did it make,,,,Only kidding
Trying to see the video, my mainframe has been done for a month and working on a 15 year old laptop
