Is it worth boxing the frame?

[Firstgenfan]

Thinking whether or not I should box the frame on my 53. It's boxed to the firewall right now. Motor is going to be a 6.0 LS style motor with probably just a cam. It might be around 400 crank horse or so. Any suggestions? Truck is going to be just a cruiser

Box it. I did mine, didn't want to take the chance.

Thanks guys. I said screw it and started the rear... should be done tomorrow from the cab back and have my pieces cut for under the cab. I'd be a lil farther ahead had my oxy/acetylene torch not been empty.

Unless you are running a BIG motor and BIG tires, personally I say it doesn't need to be done. And be very careful doing it, you CAN knock that frame out of square welding too much too fast.

I agree

I boxed my frame around my( No Limits ) Camaro clip, to right under my front cab mounts, this was to add strength to the clip. about 13" total
Also, boxed the frame after C-notch the rear, went from the shock cross mount forward about 20"

I may add another plate (12") just in front of the front rear spring perch and crossmember for a little more strength .

But I think boxing the whole frame is overkill for a driver.
A few plates added to the frame will stiffen it a lot.
You'll be breaking the tires loose and smoking them for some red light fun.
If you plan on putting on some slicks going to a sticky track and doing hole shots I would say box it

Boxing the frame is overkill for a street driven car. For 400 horses I sure would not worry about it. Box the frame where you IFS goes. From the front to about the fire wall is typical Why? Because the original frame was a c channel and designed to flex and help the straight axle suspension. Once you install IFS there is no longer a need for the frame to flex. It is actually better to have a boxed and stiff frame in that area and let the IFS do its job.

That being said I did box my frame from the rooter to the tooter. Why because I like the way it looks and plus I'm known to it a little nutty.lol

Rear is tacked in on both sides and I have the pieces cut for under the cab. No turning back now! I MIGHT turbo this truck down the road so I figured I'll just do it and it's done. Thanks for all the responses!
