Have never scaled that heavy of a car, however, I shoot 52% to 54% in the front. There are other variables to consider such as the wheelbase and type of suspension.

At that weight I don't see how it could not be over 50% on the rear. Making the suspension work is every bit as critical as weight distribution.

310 HP?
OUCH!

It is 294HP Iron 296HP Alum. In 72/73 Mopar with
Higher Compression

Let See: 310HP x 13.5 (L) = 4,185+ 170 (Driver weigh is added) is a total of a Svelte 4355 for L/SA
if my math is right.
Very Tough Way to Go!!
I race one of the fastest 400's in NHRA and this Combo would NOT be a dime rocket at that number
to get even 2 or 3 tenths under the index.

If you have the car and really want to build a stocker on a budget = 360 @ 276 would be much better
easier way to go on a budget - We ran the 360 for years
276HP x 14 = 3860 + 170 =4030 @ M/SA

This would be doable on a budget and I would be happy to help
Better plan on a Dana 60

3400 LBs is way lighter than we could ever get a Cordoba with a big block or even our
Satellite and we TRIED!

John is spot on here. By far the The best combination here. The transmission will cost a quarter to build. Everything about this combination can be done fairly reasonable
