I've been 5.08 and 5.09 with a 1.18 60ft. In 1/8 mile. 580in A-head motor on a single fogger I have been thinking about upgrading to the aftermarket lowers. In your case with a new fresh build I probably install the aftermarket stuff.

The uppers are reinforced because they were pulling apart and the lowers are tacked with the reinforced kit added

If your uppers are not abused I'd recommend welding them and running the support tubes from the inside of the upper boxes forward to the main hoop.

But if you're looking for the maximum in adjustability of the upper arms (think ride height here) then just go with the aftermarket stuff and be done with it...

Going fast on the stock torque boxes isn't the problem, having them last is.

Weld, Plate and sandwich bolt them up and do Like John suggested by adding bars from the cage to the mounting points.

Here's what you do Nick...

Mock up at ride height and see what the intersect points look like and if they'll work with the power you plan to make.

The rear suspension bars in a Fox like a certain ride height to get the correct instant center (IC) and let the rear suspension function properly. Raising or lowering the ride height affects the IC.

If I was building one with stock suspension and a high HP/torque engine I'd make sure my ride height would put the IC where it needs to be and let that determine the money that needs to be spent...

Do you guys have an opinion on whos upper and lower boxes are the best ?

TeamZ are good. I run UPR on my car. Baseline suspension seems to have some nice uppers that I want to try.
