We got to 2250 with a 604 crate but 2300 is a low weight for an iron block car to get the numbers right.

If it is a dart block and 2 inch car; you are going to be right at 2350 if you put every other part on the car on a diet. It is very expensive to lose those 50 pounds with lightweight components. radiator, and dry sump lines to move the tank. It can be done. I think the 50 pounds heavy aslo help sometimes when the track slicks off. We have that combo and it will be at 2350 to 2400 pounds.

JJRT would bet you would have trouble geting under 2450, I had a 06 1 3/4 roundtube with a bowtie block and aluminum heads was about 2380 at 55% rear and I weigh right at 200.
