What combo are we talking about here?

4,200 pounds?

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

no valve train, interior, converter, fuel system, drive shaft or fluids yet, car was heading to scrape yard, got it for zip 400/727. I had spare 727 with light weight parts/TA valve body

Re: 4 corner weight b-body
 
SO now we know the combo, anybody have any percent/weight suggestions?

Re: 4 corner weight b-body
 
As close to 50/50 as possible should be fine.
Normally hard to not have WAY more than that on the front.
Very heavy front end components and stock brakes
are boat anchors if you budget will not take aftermarket
expense.
Our Roadrunner 400 I/SA @ 3700lbs. split two 8 3/4 case clean in two
and we would have been out of luck at a national race if
our friends the Cotton family had been kind enough
to loaned him one!
