Quite honestly, do you think that 50 lbs will have any significant impact in performance?

TOTALLY not the point Jeff. Any extra weight is a pain and a detriment.

The flip side of this is that I'm convinced after looking at dyno sheets and having experience with making large displacement motors with low stock hp "work" in IT that the Vette's 350 is going to see big gains. The intake is an issue but that is not where IT flow improvements are seen. You need to scavenge and you put a great header design on that car and you are going to move the torque peak up a lot if the cam has some overlap.

With all due respect, you need to do some more research on the intake and how crappy it is. Every engine has a bottleneck and if the intake is the weak area, there will be no huge gains to be had if you can't get enough air in to make a difference. Frankly, the routing sucks. Builds have been done on these for decades and all the hop-up stuff just isn't IT legal.

I suspect you guys know this which is why the car is being built, and that's fine. You are entitled to the benefit of your hard work, and taking a chance.

But I think it very likely the car will make way more than 25% (but voted for it anyway because we don't have any real data to the contrary) and think keeping the DW adder in place for now is no real injustice.

We THINK it can make 25% (mostly because a nice B&B on these older motors really tightens things up), have great torque, plenty of tire, and handle well. Issues of concern are HP, brakes, and and transmission (hoping the +3 business doesn't hurt the car). There is no way to do what you did with the TR8 as it doesn't have individual injectors, just 2 small throttle bodies injecting fuel into that manifold. Much like the old-school cross-ram carburated units of yesteryear.

It IS an injustice Jeff, no matter how small you think it is. Apply the process evenly to all cars. Now you know how ITR was built, either continue along that path or put the Vette on a +50 hold and get the rest of the class in line. That ain't going to happen in the next 3-4 months so do the right thing for the member who is building the car and get it in line with the class. Right now there is a 250lb difference in a car with excessive torque and a car with 'no' torque. It adds up.
