The Stovebolt Site Forums The Shop Area Engine Shop Specs to bend header pipe - 49+ 3100 w/216

Hey all. Hope everyone is staying happy and healthy during these crazy times. Found that besides the nuttiness of working from home, I have some extra time to look at some long standing projects my truck has been begging to have finished up.

So my 52 3100 came with a pre 48 manifold installed. The heat riser valve froze (i have since freed it up) and I was having some major intake issues. It was running really poorly. I found the correct NOS Intake and Exhaust manifolds for my truck last year and have them installed, but as most of you know (I did not) the manifold outlet on the pre 48 was straight out, where the 48+ exhaust comes out at a 30 or 40d angle.

I want to have the local shop bend me a up a replacement head pipe that I can then install into the rest of the system. I looked at buying one online but with currency exchange and shipping its crazy to order one into Canada. The shipping charges are more than the part... I talked to the local exhaust shop, but to have them bend it they need the specs/measurements on the original. I am hoping one of the amazing folks here have these specs filed away somewhere. I could drive it there with just the Manifold on, but worried that with no back pressure I could cause some damage? Open to thoughts on this, as it would be whole lot easier... but not wanting to chance causing a bigger bill somewhere else...

Thanks in advance for the input!

Somebody else asked about this recently. Does this help?

That helps a bunch! I figured one of the amazing folks here would be able to help. Now to see if my local pipe shop will bend it up for me. Let you know how it works.

Thanks a ton ( or a 1/2 ton in my case )

Sweet, I worked in a Midas shop back in the 70's. I can't tell you how many pipes I bent up from cards like that as well as doing custom work on a lot of different cars.
Gord where did you come by those cards if you don't mind me asking?

I just provided a link to Tim Lederman's website.

Called around to the local muffler shops, none have a setup to do spec bends like this, but the guys at the Budget Brake & Muffler shop directed me to one just up the highway with the proper bender. $80 later I should be able to start the truck up again finally. Been sitting since last spring when I installed the new manifolds. I'm pretty tickled right now. Cant wait to pick it up Monday and install. Thanks again Gord for passing on the info, and Tim for having it online.
