Welding vs Bolt In

My C notch is all bolted in. Any advantages to welding it in after it it bolted in ?

Yes. Over time the bolts will stretch and loosen up a bit with frame flex

Re: Welding vs Bolt In

If you don't do a lot of towing and

Maybe plan on lowering it more in the near future,

I would leave it.

If you like the Stance and do any Heavy Towing,

I would defiantly weld it and take the bolts out

and use a copper spoon as a backer and weld the bolt holes up.

Re: Welding vs Bolt In

No reason not to do both. Kind of depends on you welding skills.
On my 68 C10 with a C notch I bought the frame with the weld in C notch already installed. Not sure of the previous owners welding skills I added bolts and boxed the inside of the frame with 3/16" steel plate.

Boxing the frame is a great idea. Give me a chance to use the brand new plasma cutter and tig welder that I just bought. I will just leave the bolts weld it up and box the frame. Firm believer in overkill.

Re: Welding vs Bolt In

Welds & bolts; especially if not a certified welder.

As for boxing, it will be better boxed but still won't be as strong as stock since the C-channels strength is in its height.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
