Let me help you old fellers out. Stick these on the back side of your safety glasses, welding helmet, etc.

Re: 340 upgrade
Sounds like a good idea Carl. Have you tried them?
Here are some more photos. The bumper overrider idea didn't work out so well. Too deep at the end and a bit too heavy, so I formed up some sheet metal to work. I think I'm ready to mount the radiator and fans now, once I do a little more painting. Made enough clearance for a fat filter too. JB |

Jim, I don't recognize the harmonic dampener, looks"aftermarket ? Share ? Thanks, roverman.

Re: 340 upgrade
Hey Jim,
Cars lookin good. FWIW Miller offers magnifying lenses that fit into your welding helmet. Many different styles and magnifications. They are a great help for us more "experienced" individuals . Cheers Fred |

Re: 340 upgrade
Quote: Nope. Don't quite need them. I use 1.0 readers for very small print. I did get a set of these for Robin to use behind her torching glasses. They are like the bottom half of bifocals. The pic shows the case. The lens is a half moon shape. [www.amazon.com] Fred's suggestion from Miller would be a better choice for a welding helmet. The stick on bifocals from Amazon would be better for safety glasses. |

Re: 340 upgrade/ Fluid Dampener ?
Jim, I took a "read". Somewhere-back there, you mentioned a Fluid Dampener ? Is that cast iron hub going to last ? I've modified smaller dia ones,(F.D's) from sbc's, to fit our motors. Nice work. roverman.

Re: 340 upgrade
Should be fine Art, not much stress on it I think. Didn't see any real need to go massive there. The worst loading is the blower and the biggest stress is the harmonic impulses. It's certainly not overkill but I think it'll do.
I'll check out those lenses next time I go to the welding supply, maybe they'll have some I can look at. This LCA mod has been kicking my a$$. The clearance cutout is pretty huge. After 3 different approaches failed I decided to try something entirely different. Instead of trying to reinforce the front arm of the LCA I started thinking in terms of enclosing the rack, meaning visualizing the clearance space needed and once I did that a picture started to take shape. The rack, boot, and clearance forms a tubular space and a 3-1/2" tube can easily enclose that, centered on the rack, with room to spare, and intersect the LCA forward arm in appropriate areas for welding and reinforcement. Slice off the upper half of the tube to allow articulation, round the corners and such to make it look presentable and I think I'm there. So I ordered some tubing. Next week we'll see how it all works out. It will definitely look unusual, but I think the strength will be there without adding much weight. It's been a rough week. I've had a very few small successes but overall it's been one of those days where you wish you could just start over... or not, and a week of it, and there's no reason for it. Maybe tomorrow will be better. Anyway it'll pass eventually. I probably need to get out more. JB |

Re: 340 upgrade
I'm Back! The LCA's are finished and installed on the car, see the Roadmaster thread for photos and details, same approx. date.That worked out very well and even looks good. The airbag people sent me some smaller bags and I'm test fitting them on the car but it'll take a lot more air pressure so time will tell how that works out, for now I'm thinking the original bags will be the way to go but we'll see, this option may be useful. From there I moved on to the headers, trimmed and rewelded the port flanges to match the 340 and welded on some pieces I made up for port EGT probes, drilled and tapped those to 1/8 NPT and then bead blasted the headers. But first I had to make this dust sucker for the blasting cabinet from an old dryer fan and parts I had lying around:
...and naturally it turned out that most of my beads were as light as the dust so they got sucked out too. Have to get some bigger beads. Along about that time the house AC quit and all of those hard to find bits and hard to figure out details also seemed to come home at the same time so as you can imagine I've been a little busy. Did the AC install myself and the house now has a wonderful coolness factor, plus a little side benefit is that my office now has a nice little window unit that keeps it nice and cool. I'm really loving that! At the same time I was running conduit and 4 ga wire to a sub panel to power the old house oven, getting some ceramic header coating ordered (went with Techline) and finding insulation to make an oven extender box. About that time I figured out I also need a vibratory tumbler so I went and dug a 55 gallon drum out of the shed along with some conveyer belting to pad the inside. Next project coming right up! Wonder if pea gravel will work for a polishing media? Meantime since I was looking around for something to do to relieve the boredom, I pulled the hubs and rotors off the MG and redrilled them for a Chevy pattern, along with the spare tire: That worked out so well that I decided to leave the brakes alone for now. They are plenty lighter due to the new lightening holes where the Ford stud pattern went and new brakes after all, so the new Outlaw calipers can wait. Interesting though that the outlaw calipers fit the Mustang rotors. They are 24mm thick. Maybe by the time I wear out the Stang brakes again 24mm scalloped rotors will be available. But Lordy them things is heavy! Just the brackets to match the MG spindles weigh as much as the Outlaw calipers! There's no rush. I decided the things that don't need upgraded right now can wait. Much more important to get the things done that're keeping the car off the road. Driveshaft, shifter, fuel rail and then the last really difficult piece, the air inlet and throttle body. (that's not including a new hinge assembly for the tilt front end, and I'll likely go with hydraulics on that) That will be a challenge but having done one already I have some ideas, and I have better equipment to work with too. The plan is for three main inline butterflies and below that two very small ones to be run by an actuator of some sort for idle air control and possibly throttle blip on downshift. Part of the challenge is going to be deciding how large to make these two small throttles and how to construct them. More on that later, any ideas gratefully accepted. JB Edited 1 time(s).

Re: 340 upgrade
Out of curiosity, why did you use the triple bags rather than the conventional double bags?

Re: 340 upgrade
They are taller mainly. Also the crease lines up pretty well with the mount for the bump stops so a little less grinding is needed to fit them in. But really just for a better fit.

Re: 340 upgrade
No, I'm sure they are the same. I've had both here and the diameter difference would be pretty minimal. I am experimenting with a smaller diameter bag but it requires twice as much air pressure to carry the weight. 150+ psi takes a pretty good compressor, so I'm not sure they will make the cut. You can find 80 psi shop air just about anywhere.

Re: 340 upgrade
Ordered the wheels two days ago. I'm still suffering sticker shock and buyer's remorse. Geez I hope that goes away soon. They'll be here in 3 weeks. 17 x 11 on the back and 17 x 8-1/2 on the front. Weld S71.

Those are really going to look great Jim, can't wait to see the car finished with the new blower system and IRS.

Re: 340 upgrade
Well Fred, I just overloaded on murderburger and oreo blizzard ice cream cake, is that close enough?
The wheels are polished, they are the "high pad" version which gives more brake clearance and has kinda curved spokes since they came the closest to my ideal offset. 43mm offset on the rear and 24 on the front. Anyway it'll make things a lot easier when I go to fit up the light weight brakes in front. So now I get to sweat worrying that the offset is going to be right. It might not be that big a deal, except that they cost almost twice what I paid for the car. OTOH, factor in inflation and maybe they cost less than the car. I can't figure out if that is good or bad. I don't know what the weight is, I forgot to ask. But they should be pretty light. Regardless, I figured this'd be my last chance before tax refunds so I'd better go for it. Edith took it pretty well. Did you ever notice that women are thoroughly confusing creatures?

Re: 340 upgrade
If you feel better Jim, then the RX is on the money.
Right there with you on the confusing creatures. Taking the lovely Lynne to France next spring for one of her culinary courses. Or she's taking me, I'm not sure. She said "we'll be near Italy maybe you should stop by the Ducati factory again and pick out a little souvenir". I said that I have enough T shirts and key chains. She said " I was thinking more like a new bike". I said ?????????????????? I love that woman. Cheers Fred |

Once you install those wheels, buyers remorse will just fade away. Should look pretty good! Bill |
