Correct, we just keep an eye on oil temp to make sure the engine isn't getting too hot. We try to keep oil temp @ 200 degrees or less. Sometimes we aren't able to get that much heat in it.

The welding and elbow were built by Tim Lyons of Lyons Custom Motorsports.
As for the dual injectors, as a general rule of thumb, that has to do with the fuel we're using and what we had available to us. Methanol doesn't have the same energy content as gasoline, so the rule of thumb is that it takes twice the amount of methanol to make the same power as gasoline. We had to sets of injectors available to us when we started, and we hoped that we'd be making some decent power, so we opted to use both sets (not to mention that a single BIG set of injectors is nearly twice what we paid for what we already had). So, in the Holley we have the primary set that runs all the time. Then, we have an activation threshold that can be set to enable the second set of injectors. The threshold is a percentage of the duty cycle of the primary injectors.
This allows us to use a bit smaller injector for the primary set of injectors to get the engine to idle cleanly and a much larger second set to help take up the slack when it's making steam.
Depending on what we decide to do this winter, we may change that up some. But all in all, it's worked very, very well for us.

The intake is a Super Victor. We had the carburetor pad milled off and that aluminum ring welded on. This was all done in an effort to make airflow more uniform between the runners given that the LS carb design would suffer a similar fate as SBF with shorter runners in the center and longer on the corners.

I have all the same parts except untouched junkyard rod bolts and rings. Went 5.76 with a little 75/83 turbo on 20psi thru a LS1 intake. These L33's are the ****! I have 2 of them and looking for another.

We've tried anything from 3800 to 4500. We've also tried 7psi to 13.5psi. It likes to be in the range of 4000 and 8-9psi for a good launch that doesn't want to drag the bumper or wheelie for 200ft.
