Ken

This is a chassis that a friend built. Note the rear suspension,

[kmeaders@q.com]

That's cool Rick, thanks. He's my kind of guy with that suspension. I've built the front end 3 times now and finally got it right. Next week I'll tackle the rear suspension. This little project has definitely got my full attention.

Ken, I got the packages from Rick with the Cosworth and what it amounts to is a bag full of parts, some cast in metal, a few resin and plastic parts. It appears to be parts that while well done probably originated as one of the older 1/8th kits that were cast.

The CD has some copy in a language that I don't speak but there are some pics of the kit engine being assembled, no dimensions or any of that. If you'd like I will copy the CD and send it to you or I can post them here in your thread (if you'd like) for reference.

When I get the time (yeah, right) I'll convert what I have into a street engine...but I'd be more than happy to supply you with pics of the parts etc. if you like to try to scratch build one.

[kmeaders@q.com]

Thank you Don. Posting some pictures would be helpful. If you could measure the motor (without any external parts like pumps, etc.) That would be the biggest help. All I really need is the length of the block; the width at the pan and at the top of the heads. If it's 1/8 scale I'm sure I can take it from there with all the pictures I have collected in the past few days. I just need a starting point. Thanks again for the help.

[Don Garrett]

No problem Ken, glad to help. I'll post pics and measurements a.m.

[Rick]

Ken, if it helps for your research, the kit is of a 1977 DFV Cosworth F1. I can't remember the name of the kit manufacturer other than that it was a very rare 8th scale kit.

[Don Garrett]

Ken.....these are just some of the parts (yes, there are more)......as you can see it's a fairly complicated engine especially if you are going to scratch build one.

These pics are just to get you familiar with the chunks that I have...I'll start posting photos of the basics items, block, heads etc. and you can tell me as you go along what measurements you need to get started. It'll be easier that way and I won't have to load a gazillion pics at one time.....if this works for you I'll start with the block, it's 2 pieces and would make sense to construct it that way.

[Don Garrett]

I think these are the parts you'll be most concerned with for right now......

[kmeaders@q.com]

Wow Don, thank you. I think that is enough. but I won't know until I start laying out and building the motor. That's is a very nice and detailed model. I'm not sure I can make it that good, however I can get close. I owe you one.

[Don Garrett]

You don't owe me diddly Ken.........I'm more than happy to help you any way I can.
That's what Scale Motorcars is all about.
Besides, that's what I get the big bucks for.....Dan (owner of the site) sends me a box of peanut butter girl scout cookies every month.

Good luck with your build and just rattle my cage when you need measurements.
In case you're wondering, the engine that I have here will ultimately wind up in a Madd Fabricator belly tank or I may scratch build a boat-tail roadster to put it in.

Ken, the engine you are going to build is a perfect fit for the "Scratchbuilt" catagory in the Engine Building Show. In particular, in progress photos and commentary describing what you are doing and how you do it would be a great addition to the show.

Are you up for it?

[U]Cosworth Ford DFV V8[/U]

Description: 90° V8 crankcase and cylinders cast together in aluminum. Wet cast iron cylinder liners sealed with O-rings. Steel, coated iron, and nikasil alloy liners were also tried. Nikasil alloy liners saved 8 lb in overall engine weight, and were standard by 1983.
Weight (with clutch): 370 lb / 168 kg
Overall width: 27.0" (686 mm)
Overall length: 21.5" (545 mm)
Bore: 3.373" / 85.674 mm
Stroke: 2.555" / 64.8 mm
Bore spacing: 4.100" / 104.1 mm
Deck height: 6.505" / 165.2 mm [I](crankshaft centerline to deck surface)[/I]
Crankshaft height: 5.23" / 132.8 mm [I](crankshaft centerline to external sump bottom)[/I]
Cylinder stagger: 0.375" / 9.5 mm [I](left ahead of right)[/I]
Materials: Cast aluminum block and head, forged steel crank and rods [I](earliest DFV cranks were billet)[/I], forged aluminum pistons, cast magnesium covers.
Firing order: 1-8-3-6-4-5-2-7
Compression ratio: 11.0:1 (approx.)
Fuel: 101 octane (M.M. - motor method) minimum
Rotation: clockwise when viewing front of engine
Mounting: At the rear end of the engine are suspension attachment points, and at the other are car attachment points at the top and bottom of the engine. The top chassis mounting bolts are part of the cam cover, and have 4 to 6 bolts per cover per end. The lower mounting bolts are part of a bracket bolted to the sump assembly. The lower bolts are located 9.0 inches (22.86 cm) apart. As the engine expands when it gets hot , the mountings are made so that the sheer forces are concentrated on the bottom bolts.

Yes Sir, I am.

I'm moving right along with this strange hot rod. Finally figured out how I needed the front suspension to be and have almost completed the left side. Two aluminum bulkheads tied together by the four frame rails that will connect to a rear bulkhead. Started the rear assembly but got off on a " how is this motor going to work" tangent. I also started drawing the motor to scale using Don's pictures and Google info. Anyway I do have a master plan and all this will come together. The Cosworth will sit in the front like a traditional T-bucket but enclosed. I am trying my hand at louvers because this car needs them. The coil spring is made from rebar tie wire, I wrapped around a pencil and the body from aluminum 1/4" tubing.

Started on the Cosworth. Kind of fun as it's not a Chevy small block and I really have to figure out how to get the illusion of being a 70s F-1 motor. I started with the oil sump and, as you can see, also started on the block. It will barely fit in the T bucket body because of width. This is something I would have never attempted 3 months ago.
