Thanks for that.
So, a McSorley 442 chassis should work for me right? 4" wider from the dash back, the front is by the book.
My shoe size is 10-1/2, I'm 198 lbs.
I don't have a donor yet.

Word of caution here. McSorely has more than one 4-4-2. One is as you describe it, the other is +4 over the full length of the car, and requires a custom nose cone. I can't remember if there were others (bad case of senior-itis here). Perhaps the other guys can help you out here!

Yes, I know. Not the 400, or not the 442E, the 442, which is wider by 4" in the passenger area only.
"An increased width, length and height using the nose cone and suspension mounting points suggested by the book. The increased width exists through the rear and the cockpit, while the front end is based on the book chassis and it uses a standard nose cone. The suspension brackets can be mounted according to the layout provided by the book, but the length of the front wishbones should be customized to be sure the track width agrees with the donor axle following assembly.

The increased length provides an additional two inches for the pedal box and another two inches in the engine bay. The increased height goes through the horizontal portion of the chassis (forward of the dashboard) to balance the over all design and accommodate taller engines. A standard nosecone that is 26 inches wide at a distance of 12 inches from the front should fit with little-to-no modification, although a tall "cowcatcher" is called for to bridge the bottom of the taller chassis with the bottom of the relatively stout nosecone.

There are some vendors manufacturing nosecones that are taller than the book design to provide even more height for the engine. For example, Champion Motor Cars used to produce an oversized nose cone that sits 13" below the top rails and an additional 1" above the top rails... placing a full 23.5" under the bonnet while leaving a relatively small 2" gap along the bottom of the 442 chassis. This oversized nose cone is still available from certain vendors. A standard book nosecone leaves a 5" gap along the bottom of this super-sized chassis, but the width is spot-on."

I might add that Kinetic Vehicles offers a 4" insert for the nose that allows you to cut and widen the nose up to 4"! https://www.kineticvehicles.com/parts.html There are many options available to you!

Thanks you. I have found Kineticvehicles on the forum already. He is a member here also.
I'm looking at the 442 and 442E by switching the pdf files between the two drawings(bottom rail layout) and to me it seems like the 442E is wider at the pedal area, but shorter, than the 442.
Since I'm not that tall guy, that would fit me better? I could use more pedal area(width) then length, right?

The 442E does provide more "foot" room at the pedals, which is important. I still had to recess the right side inner wall of foot area as shown in the attached photo. This photo is a little misleading. The pedal pads can be adjusted to provide more space between them and the gas pedal can be adjusted (as not shown in the photo). The end result is plenty of space for my 10 1/2 shoes.

Cheers,
Roy

Here's a little detail of the final configuration of the pedal area. I adjusted the clutch pedal to the left so there is more room between the clutch and brake pedal. The Wilwood pedals are great for this.
The gas pedal has a four position adjustment in the horizontal direction so I can still move it more to the left if necessary. Also I made the gas pedal pad adjustable vertically about 2 or 3 inches if needed. And I still need to protect the clutch bleed nipple (black dot on the right of the gas pedal) as suggested by Mnot in an earlier post. But all-in-all there is plenty of room.
Cheers,
Roy

Thank you for those pictures, they help a lot.
I guess then I will go with the 442E chassis.
Can I have a wishbone suspension, at the rear with this chassis?

Yes, but by using the 442E drawings as guidelines, you would have to redesign the rear end of the chassis to accommodate an IRS. For my first Locost I used a Miata positraction IRS. For my second I used a Honda S2000 IRS.

There are no drawings, to incorporate a 442E chassis with wishbones at the rear?
These McSorley chassis require the Miata subframe?

"Thanks you. I have found Kineticvehicles on the forum already. He is a member here also."

Did I fail to mention that I bought a partially finished car from Jack last Summer. Great guy to do business with!

The Vodou rear end could be used with the McSorley chassis?

You got lucky.
I want to do everything myself from scratch. I also want to learn how to weld.
I'm a machinist, but I have never needed to weld anything yet.
Our company has two devices on the rover(!).
The brush you guys see on the TV, when they show a rock on Mars, it was developed by out company years ago.

I feel the OP is looking for a "complete" set of drawings, dimensions and instructions to cut and weld a chassis and suspension with no re-engineering work required. That, I cannot do.


Actually, that is what I was hoping to find.
So, there is no such chassis drawings?
I should use the 442E, and modify the rear end with the Vodou rear end parts, and use a Miata differential?
I have just got the "Book" from the bay. I'm reading it now.

There are more than a few who have published electronic design files here for frame design.
You are not likely to find one that fits your plan perfectly.

Mc Sorley provides IGES files that you can plug into solid works or fusion, etc.
