LFD's 41 chevy Project "Fill-in"
Since we don't have a section for the real old stuff I figured I would post it here so any LFD fan can see some of my other work. I call this project Fill-in because it has been sitting in my shop for going on 2 yrs now because it was supposed to just be fill-in work to keep busy. It belongs to a friend of my wife's and I have been so busy with other work I never had a slow time to work on it for any good length of time. Well that time has come!
I finished my frame table a few months ago in preparation for this job (then my Tahoe next) so I would have a flat surface to work from. The table is leveled with a lazer and is with in 1/32" and the top of the table represents the ground so all measurements come off the top rail as 0'-0". I have the lazer set up for dead center as well so it makes getting things even real easy. So far I have had the frame blasted then I boxed it in with 3/16" plate (these frames are very thin and flimsy) front to just behind the IRS unit. I installed a TCI tubular MII kit up front with Bags, Power Rack and a sway bar. Then out back I am we are doing a 93 Lincoln Mark VIII 8.8" IRS with aluminum center section and lower arms also on bags and the factory sway bar was able to be used as well. It has a pumped up 350/400 combo and the body is very strait and rust free. Our goal is to eliminate all frame flex and let the suspension do all the work like it should. Today I started the tubular back bone of the chassis and I used 1 1/2" .095 and .120 wall tube. The top tube is flush with the top of the frame and the bottom tube is 3 1/2" below the lower rail so that way it is flush with the bottom of the running boards. This will help protect the fiber glass running boards and it also allows enough room for the air tanks and exhaust to run in the tube structure and frame rails. The clearance on the drive shaft is very tight but since it is an IRS I didn't need to worry about travel clearance. Next I will install the poly tank in back and get my order list together for brake and fuel lines and the exhaust system. I hope to have the chassis in paint in about 2 weeks. Kevin LFD Inc.

Re: LFD's 41 chevy Project "Fill-in"
Yes and no! The SHO and V8 t-birds came with 8.8's but others came with 7 somethings. The new Mustangs also have 8.8 in both straight axel and IRS. Navigators and such have 9. somethings. The T-bird and Mark VIII (and I think the IRS cobras) have a sub-frame that everything bolts to and it is held in with 4 bolts so it makes for a very easy trans plant. The lug pattern on the T and Mark are a funky metric pattern but I have a machine shop re-drill the hubs and rotors to a standard ford or chevy car pattern for about $75.

Re: LFD's 41 chevy Project "Fill-in"
I like it when the Brown van shows up with presents. I only got about an hour or so of work on this today as I spent most of my day cleaning the yard and shop for a party we are having this weekend. But like I always say any progress is good progress.
So my summit order showed up today and I started by laying everything out so I could take inventory and figure out were I wanted to start. I figured the brake lines were as good a place as any. One thing I did not know until tonight is the IRS is all metric on the brake lines so I had to cut off the factory nut and do a metric bubble flair just for that end of the line were it connects to the flex hose. All my other connections will be a double inverted flair with 3/16" tubing. I started by mounting the flex lines so they had plenty of room and clearance to still get full travel. I am using a drill tap for all my mounting to the frame with 1/4-20's. I have the rear lines done up to the 2 lbs residual psi valve. With the master mounted up on the fire wall you really do not need a res valve but it will make for a very nice firm pedal. It is not enough to drag the brakes but boy will they feel good. I also picked up a nice little adjusting proportioning valve that also has the brake switch built in. It has (2) lines in and (3) lines out, 2 front and 1 rear and it will be mounted down on the frame below the master so we can clean the firewall up as much as practical. Also as you can see from the pic I ordered just a few mandrel "J" tubes so I can build the exhaust system around everything that will end up in the way. I will be using 2 SS flex joints to isolate engine movement from the rest of the system. This is one real nice thing about running a IRS is nothing moves so you can build the exhaust system real tight and solid. Summit sells some nice inexpensive hangers that isolate sound real well but but stop unwanted movement as well. Now I need to find some good deals on (2) 2-3 gal air tanks before I can start the exhaust system because it will be sharing the same limited space. Well more next week. Kevin LFD Inc.

Re: LFD's 41 chevy Project "Fill-in"
Well I have been filling in a few more items on the chassis. Yesterday I built the motor mounts, trans mount and started the exhaust. Today I finished the exhaust, pulled it out so I could weld it all up and coat the welds then back in it went. I ran the fuel line and finished up the gas tank mount as well. Next I will mount the Air tanks and order the drive shaft. Then before I pull it all down for final welding and painting I want to run the air comp wires, tail light wires, fuel sender wire and build the battery mount. This way it comes apart and falls back together after paint with less chance of a scratch.

Re: LFD's 41 chevy Project "Fill-in"
Man that IRS is soooooo tempting to do on my blazer especially since I know where I can get a T-bird for free. I got to quit looking at this.......(But I can't)

Re: LFD's 41 chevy Project "Fill-in"
Out of curiousity, can you tell me how much the exhaust tubing cost? Is it comparable to having someone put custom exhaust on a truck? Thanks Kevin. Great work as always.

Also depends on what you have built and by who. I have done headers in the 3-5K range for SS full lengths before so this set up was very cheap ![]() Kevin LFD Inc. |

Re: LFD's 41 chevy Project "Fill-in"
Not finished yet with the hood bracing but it is getting close and this will give you the idea of what I am doing. I made the hinges along with a friend of mine who needs the same set up for his 45. So I designed them and he built the hinges (2 sets) and in return I will make his bracing for his hood. I have already 1 pieced his hood for him.
So I made a mounting brace then the hinges mount to under the dash and a sheet metal brace for the hood. I will make a few more braces for the hood that will run front to back along the sides to take the stress of the gas struts. I used 2 gas struts under the dash out of a 2000 explorer hood hinge. They only have 2 1/4" of movement but are super strong and seem to work real well. Kevin LFD Inc. |

Re: LFD's 41 chevy Project "Fill-in"
I will make 2 small plates that will fill the recess's in the cowl I had to make for hinge clearance and they will have sweep seals on them as well.
