Re: 56 pro touring build
Been working on the roll cage and figuring a way to make it so the cab is removable in the future. Bent the main hoop and a cross member for it so it could fit into the hollowed out area beneath the window. Used roll bar flanges that I bought from chassis engineering. As a side note, they are suppose to come with grade 8 bolts but they put grade 5 in the package. Had to call them on it and they fixed the problem. Nice pieces.
Build the rear stays (at least part of them) and then the upper shock mount. Dirty work! Need to do the other one and continue the cage. Last edited by hotrod1; 07-05-2011 at 06:54 PM. |

Re: 56 pro touring build
Ok guys, we need your opinions even though I know that this roll bar stuff is not most peoples bag. One thing that you guys do know well is METAL. Just to clarify, this is a pro touring-build. That is why we are putting in the roll cage. Anyways, got a little carried away bending the front braces to go around the dash. It has its share of bends but contours around things good. The question is, it this a foolish to have this many bends and contour as they weaken a cage too much? Or is it minimal and no big deal. Should we stay with a straight bar down from the top bend which goes to the main hoop?

Also, you may want to hard-mount the body to the frame with no bushings between it, otherwise I could see it tearing the cab around those plates on the back of the cab and on the floor.

Re: 56 pro touring build
thanks for the reply. You are right. Our bar is bent too much. We will probably redo the a bar to maybe something like this truck (picture) has or maybe even straight. It is difficult balancing between safety and ease of use.

Re: 56 pro touring build
I looked for information on building or mocking up a cage. Could not find too much on certain things so I thought that I would share some things as I go along.
Measure the bottom of the main hoop and determine where your hoop meets the floor. we then cut a small hole in each side of the floor to put the main hoop through. We plan on using connector plates through the cab and down to outriggers to the frame for connection. We want the cab to be removable. After fitting the main hoop, cut the bottom to the length desired and then weld the floor cutouts back in. |

Re: 56 pro touring build
The back portion of the frame/chassis and cage. Overkill, but there will be minimal flex as a result.

Re: 56 pro touring build
You can NEVER have enough cage!! Overkill = safely leaving the confines of your vehicle when it ends up on its lid!!
Looking good so far. Ratty 46 |

Re: 56 pro touring build
Looking good. Sounds like you need a break from the dimple die and go back to the tubing, lol. Lots of work but think of all the $$ you are saving. I don't know because I am asking but BLUEJEEP said .... Also, you may want to hard-mount the body to the frame with no bushings between it, otherwise I could see it tearing the cab around those plates on the back of the cab and on the floor.
What about solid aluminum bushings? I guess I would have to have someone draw a pic. lol so I could understand.

Re: 56 pro touring build
I've been looking at your pics and as long as your not going to drag race it at an NHRA track the curvy bars should be fine if you have it connected across the top front and back and a mid bar in the middle of the dash. I think to fully secure it you will need to have runners going to the front of the frame.
On the rear, where you have that what looks like a temp bar. Is that your coilover shock mounting point? Is that also at ride height or will the rear be lower from the frame than it is now? Before you go any further I suggest you either stop by a pro chassis builders shop or have one come out to you to look over your work. After everything you have done it might save you some headaches latter on. If I were still in Cali I would go to: Chuck's Performance Welding (562) 461-9649 He did the cage on my friends truck which you can see at www.kellyandsoncrazypainters.com its in the gallery under Green Tandem |

Re: 56 pro touring build
Hi Guys:
Thanks for the feedback. We did get solid aluminum stock to make solid mounts. Appreciate the suggestion. We have also mocked up the truck to see ride height. The lowest part of the cab will be about 6" from the ground. Maybe 1 to 1.5 inches of rake at most. We are probably going to recess the firewall more so we can move the engine 3 to 4 inches back and drop it another 1" to account for better center of gravity and weight distributions. Now we just have to figure out a different motor mounting system because we had the engines weight distributed on the front cross member. It is an evolving project doing and then redoing things. I guess as you get more information from people (like in this forum), you then find different ways that you should have done in the first place. |

Re: 56 pro touring build
Your welcome HR1, The truck started out like any other. Mild smallblock and just a driver, but he came into a large bonus and started out building it. Its a near 1000hp BB Chevy and he drives it every where. He had Mickey Thompson pro street tires that lasted about a month then switched to dirt track rubber for a harder tire.

Re: 56 pro touring build
Just remember to make it stronger than you think. You always seem to add more HP. Flex is not your friend.

Re: 56 pro touring build
Actually let me say this another way. Triangulate and think through your design. I doesn't have to be heavy to be strong and resist torsion.

Re: 56 pro touring build
That '55 has to have some decent power to motivate it wheels up like that. It gives me goose bumps.

Re: 56 pro touring build
We have a 21 gal tank that sits in the back to help distribute weight. It slides in from the back. Wanted to make sure that it is protected from steep driveways so we build nerf bars to drag before the tank. Not an easy thing to bend a bar to match up with the frame tubes. You have to be right on. Scrapped a couple of pieces getting them correct.
