I know Don, things change. For a mild 380 inch street motor, with truck heads, that idles at 850 and makes 550 horse how could anybody be disappointed? I am amazed how well this motor runs. It was run on 110 fuel and 34 degrees timing. I believe this motor would be happy at 30 degrees and 93 pump gas as well. We may find out what it does in my impala. Time will tell.

Congratulations Brian, awesome job and great results!!!!!

Congrats Brian, for as nasty as that 380 is..............x2 on the killer good looks...........you hit it out of the park.............

Really cool build.........

Well, we just got home. The results...............552 horse 5900 rpm and 534 torque 4400. I am very pleased. It ran smooth as silk. We made absolutely no adjustments to anything on the engine. Fuel was right on the money, and timing was where they wanted it. I asked what they would want to change, and they said not a f ing thing. They figured maybe 5-10 horse may be found with a bunch of testing, but that small increase is not worth the effort in my book. We made 5 pulls and we were done. Jason, if you could post your videos that would be great. Thanks for the encouragement fellas.

Better put a raw egg under the loud pedal if you want to stay in the 10's!! Nice work!!

I think it'll go low 10's on a high gear only run!

Thanks guys, here are a few charts from the dyno run. Not sure they will be clear enough, but I'll try.

Hp and torque graph.

Fuel the chart starts at 3000 rpm and goes to 6000 rpm. I zoomed in for clarity. O2 sensor readings on the right.

Now that's one flat torque curve!

Wow! That came out great!
The flat torque curve is really cool.
It's a nice balance of power and reliability.

Out of curiosity, at what rpm would you shift? I can't imagine there is a bad point to shift at.

 

[Don Jacks]

57-5800 Radar,once he gets used to it.Till then.basicly high gear only runs.

Looking at those dyno numbers with less compression makes me wonder about what my build will look like and if I'll overshoot street-ability.
Guess I'll have to find out when I get there.

Nice job Brian!
