Be sure to watch the video of the fuel pressure, it will explain a lot about the results shown here. I was expecting about 350-375 lb-ft/350/375 hp. Once the fuel pressure issue is corrected I should be at or above my expectations.

You know Phil, it's hard to sympathize with a guy making 340 ft/lbs of torque while running out of gas ;)

Rob,
You really made me laugh out loud, I didn't think of it from that point of view. It was great seeing you and meeting your dad.

Was it the A/F ratio that gave it away?

Jim,
The "emergency" fuel pump I got from O'reily's ran out of capacity, which dropped the pressure, which caused the A/F ratio to hit 16.3:1. She basically ran out of gas above 3500 rpm. Calvin videoed the fuel pressure gage on my last run.

Hmmm. Hope that doesn't happen with the Roadmaster, but it could.

We didn't see evidence of that on the Roadmaster pulls. A/F looked good

For comparison, here's the last dyno sheet from the RV8 race car. 3.5 with 390cfm carb and additional restrictor plate underneath.

2 pulls with timing at different settings. The ECM adds 21' @WOT when optimum conditions exist..1st run at 13' base and 2nd done at 14' base timing. The 2nd run yielded top reading. The reading at 13' & and a earlier one @15' were close. Appears the 5.0L does best at 35' total timing. Figures not up to LS3 and 350 CID +, but respectable.
SAFETY FASTER!

No sweat, Kelly. That 300 ft/lbs of torque at 3800rpm is a blast!

Thanks Carl, try to built them where we use them! BTY, 4 tanks of fuel had 30 MPG at interstate speed.

Here's mine from Palestine. Rover 3.9, fuel injected. Megasquirt ECU with Innovate wide-band O2 sensor. Don't have it controlling the timing yet - just the EFI. 198 HP, 220 lb/ft Torque.

Wayne, your figures look real good. If you figure the RWHP and RWTq at 15% PT loss,, that's excellent Flywheel Performance. there's more available when you intergrate your timing to your ECM.

These are great numbers guys. Glad to see more people posting. I noticed that most of the posts are from warmed over engines and hope more people with standard 'as the factory provided' engine owners chime in. My numbers are from an almost completely factory engine. Not so much as a gasket replaced.

Also, who has the highest known numbers in a conversion LBC? Anyone know or should we accept the numbers here as the most that we know of so far. I know there are a few warmed over LSx engines in MGBs and TR6 as well.

-BMC.

Mine is a bit of an odd build. I have had many "zinger" engines, big hp #'s, but all stellar performance happening above 4000 rpm. I gave up around 100 hp on the high end of the rpm range, and built a sbc 383 stroker, aluminum heads, 10.27 to 1, with cam and quench areas of combustion chamber set up for torque at the lowest possible rpm. It is a hoot to drive, 1790 lbs and a Tremec TKO 600 5 speed 0.64 OD. Torque peak @ 2800, hp peak @ 4050.

This is chassis roller numbers, not an engine dyno. My ride has had both with other engines so I can extrapolate the higher engine dyno #'s

And the run that generated the above.
