From my steel hood, 4.5” hemi scoop and stock hinges to Fiberglass hood and lightened hinges was a 38lb reduction. The picture below is the fiberglass hood and 3” hemi scoop and new for this season.

So, basically double what a single plane, single carb, aluminum holley would weigh. Looks like a crossram and glass hood, and a single four and a steel hood would be almost a wash, weight wise.

I weighed the Indy single plane 28lbs The carb cover is 3.1 oz lol.So the crossram set up is 24lbs heavier
Yup that is what it is.
In the picture below is a Indy crossram with Edelbrocks and beside a Super Victor and 1050 Dominator.
The weight was 54 Lbs for the Indy CrossRam and 27 Lbs for the Victor/Dominator.
That's why the Single plane and Dominator are reputed to be quicker. They weigh less. Oh, twin Holleys are about 6 lbs heavier than the pair of Eddy's

So it should run exactly the same with 2 carbs, all sorted out. Ish. We'll see hopefully.
I was going 10.45 with 2. Switched to 1 and it went 10.37. Weight had a factor in the difference.

Last year when I put the single four on, I picked up two tenths. Hopefully I can get it to run 1080s with the cross ram.

Well if that Indy is MW port - I may be able to take it off your hands if you decide to stick with the cross ram. Plus there would be no shipping
put a couple of holleys on it and watch it fly...
Mine with AFB's, best ever 9.00@149. With a very nice set of cutom built Holley's, 8.96@150. I will say the Holleys are quicker in poor air than the AFB's by maybe a .10

these r my race units, 750 holley XP's on my original stage 3 X ram. infinitely adjustable.....
