426. I was just wondering if you did a base pull on that dyno in stock form so you would have a close HP gain number. Not all engines wil be exactly 426 in stock form.

Another question, I see the throttle body is not stock on the engine dyno. Would that affect the numbers? Are you going to do a chassis dyno with it installed in the donor Camaro?

How much does that monstrosity weigh

Exactly. I bet most guys would be shocked to learn that a stock LS3 will be well above 426 flywheel hp. As for the throttle body not being stock, they probably had to run a cable operated setup while in the dyno cell.

Unimpressed with the 3 90 degree bends before each plenum. Good design in theory, but executed poorly imo. It would work much better as a dual throttle body intake, deleting all the bends. Also severely doubt the power claims.

The dual plenum has some advantages where the runners have a "mail slot" from the first plenum so the force of the air coming in doesn't give uneven distribution to the runners. I can't see this system being anymore streamlined unless a plenum was in the valley some how.

Now, will this fit my L92 motor with the high alternator on the drivers side and a A/C compressor on the passenger side? I could probably modify it up to make it work as I have more hood clearance with my 1965 Skylark. I would love to have over 500rwhp.

As to the heat soaking most of that could be solved with a ceramic thermal barrier coating. Kind of like hot coffee in a styrofoam cup with very little heat transfer. However that would probably add $200-300 more dollars to the cost.

Looks cool in theory. I just don't see the practicality in it. It takes up a huge amount of space.
