Is the 3595 with or without the 200lbs of ballast?
What does it run without the ballast?
Any pics of the intake/carbs?
I’d suggest seeing if you could borrow something like a 440-3 and a dominator so you’d really know how much that intake & carbs are costing you.
9’s??
Sell your short block, build a bigger one.

3595 withput the 200lbs ballist. I did not get a chance to run it without the ballist. I run NSS class so the dual quads are required. I'll post a pic soon. Is the 3595 with or without the 200lbs of ballast?

You are correct Andy I do run NSS so the dual quads are required. This intake top and divertor combo I developed for a buddies 500 low deck NSS Dart so figured I'd try it myself. 700 hp should be enough to get you into the low 10's or maybe high 9's if everything else is perfect. You can make 700 hp with that long block but you're going to need to get rid of the Mod Man intake. If you need to run dual carbs for NSS then you might have an issue. There aren't a lot of dual quad manifolds for MW heads that work all that great. I'd suggest putting a ported Super Victor on there with a good 1050 carb and see how fast you can go then try to figure out if you want to go fast or if you want to look cool. There are some guys going fast with the Indy bathtub intake so you might ask them what their combo is. I think they usually have much larger engines. I've run the bathtub a few times and they work better than an old cross ram, but they still aren't great. Indy didn't even provide a gasket between the top and bottom half. Maybe they've fixed that by now?

If you are going to do all the work to update the rear suspension, skip the ladder bars and go right to the 4 link.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Andy. Is that cam capable of producing 700hp? Shouldn't be a problem. I made 775 hp with my pump gas 470 using TF 270 heads and a Comp 264/268 roller cam. You have more compression than I had so you should be able to make more power. The difference is I was using a really good intake manifold plus I probably had some other tricks that you don't have. https://www.hotrod.com/articles/dyno-tested-vacuum-pump-help-engine-make-power/

[Andy your articles are why I bought the 270s. I do need to port the intake as it does have huge steps on the roof of the runners where Indy did the cnc port match when opened to MW port. quote=AndyF] Andy. Is that cam capable of producing 700hp?

Its coming out anyway so a trip to the dyno may be in order. I'll what I can do on barrowin a good intake a carb to make a comparison. If you're serious about running 9's then you should pull that engine out this winter and put it on a dyno. Buy or borrow a good intake and carb so you can run a comparison. I bet that the Wilson ported intake that I was using on my engine would pick up 50 hp over your current intake. But you aren't going to know it until you do some back to back tests.

What is a good startin point for a 4 link setup. I'm thinking 55" out 7" off the ground. Any recommendations? If you are going to do all the work to update the rear suspension, skip the ladder bars and go right to the 4 link.

Brent Wheeler runs a 500"? with a Mod-Man. I believe it has run 9.50. My N/SS car runs 9.25 on ladder bars very effectively. Been 1.240. No need for a 4 link. Not all associations allow 4 link. Doug

Doug I think Brent is running a 540 and I'm interested to see what happens when he installs my raised top and divertors. Brent Wheller runs a 500"with a ModMan. I believe it has run 9.50,5". My N/ss car runs 9.25 on ladder bars very effectivly. Doug

Bruce Lang is running a 470 in his 68 NSS barracuda with the TF270s and a Modman with 1 1/2 spacer best of 9.48 @ 3200 lbs. I just can't seem to get my combination to work that well. Primarily was wondering if I needed to go with more duration on my cam, like 280ish. Sounds like a good idea. A couple of days on the dyno swapping intakes will give you a good baseline to work from. I have a customer with a similar car and engine combo to what you have and he runs high 9's. The biggest difference is he has a ported Super Victor intake and he is at 3400 lbs on the starting line.
