MY SBC 400 DYNO Yesterday WOW, WOW, WOW

First I would like to thank everyone for their advice and help getting me through this rebuild. I could not have done it and achived the results without your help.Thanks a Millions....
Here are a few number from my dyno yesterday, I will scan and post later the actual dyno sheets. We made about ten pulls after breakin and I was glad to spend the $300.00 for what I found and learned yesterday. The engine combo is in my signature.

Pull #A1967
Carb:4779
timing: 34
Dist:msd 85551
4300 rpm: 502.4 tq
5800 rpm: 464.9 hp

Pull #A1963
Carb:4779
timing: 32
Dist:msd 85551
4300 rpm: 495.4 tq
5600 rpm: 455.2 hp

Pull #A1963
Carb:4779
timing: 34
Dist:msd 85551
4300 rpm: 502.4 tq
5800 rpm: 464.9 hp

Pull #A1973
Carb:3310
timing: 36
Dist: H.E.I.
4600 rpm: 484.0 tq
5600 rpm: 466.5 hp

Pull #A1970/b]
Carb:3310
timing: 36
Dist:msd 85551
4700 rpm: 479.3tq
5600 rpm: 459.2 hp

Pull #A1971/b]
Carb:3310
timing: 37
Dist:HEI
4600 rpm: 481.3tq
5700 rpm: 457.5

The double pumper 4779 out perform the 3310 throughout the entire pull. Lost about 25# of tq with just a carb change.

At 5000 rpm's with the HEI and 3310 we had 471.8 tq and 449 hp and 6000 rpm's with the HEI and 3310 we had 402.5 tq and 459 hp.

She was still pulling at 6489 rpm with 352 tq and 434 hp.

Thanks everyone, but I need a double pumper with staright out the box 70/80 jets what his carb had...

The average fuel F #/Hr was:
3310-173.8
4779-163.5
The smaller carb required more fuel

Very nicely done, hope this will solve the silly vacuum secondary/double pumper comparison argument that pops up from time to time.. To make torque you need fuel.

Very respectable numbers.

Wow
You can have your engine on a Dyno for 8 hrs and only cost $75.00, that shop must have very little overhead and little paychecks.

My Cr: was 10:48.1 according to Pat Kelley Calculator and quench of .041.
Here is my complete Combo Mostly every part was new, so it can be done cheaper. The only parts I orginally used of my old engine was the Edelbrock RPM and H.E.I Distributor w/ MSD Module and Accell coil, cap and rotor. This is a 95% street car...
We also use his headers because my tight shorty clearance headers would not clear the bellhousing on the dyno stand, His headers was the 1-3/4.

No,no,no... $75.00 for 3 dyno runs. Not 8 hours worth of runs heh. Did'nt know you had it on there that long.

Heh, that just doesnt sound right "Not 8 hours worth of runs" but I think I'll leave it
