Here is a few photos of my LoCost. This car was built from a CMC do it yourself kit (pre-cut tube & bodywork), and is now drivable. There is still lots of details that are not done yet.

The engine is a Mopar Midget sprint car racing engine w/ the A-4 block and W9 cylinder head.

The front spindles and brakes are Mustang II
The rear axle is a Toyota Corrolla GTS
The trans is an AX-15

Makes me want to hurry up and get mine done! Is your frame painted or polished and cleared? It sure looks shiny :)

Interesting engine choice, very clean looking. I like the color. Is that half a 318? Did you go with a holley 400cfm vacuum secondary or a 350 2-bbl? Holley used to make a prgressive 2-bbl based on the standard single throttle shaft 2-bbl. It worked great on small street engines. It has much better throttle response than a 350 2-bbl at low rpm.

The frame is painted with silver paint. I wish I had used powder coating instead, since it is already starting to get a few small rust marks in some areas on the frame.

This engine is half of a Chrysler/Mopar 340 engine, and is a pushrod style engine. I have tried both the 350 CFM and 500 CFM Holley 2 barrel carbs (non progressive style), and I think the 500 CFM is a little better with this engine.

Thanks,

Jim

I looked up that engine, man they are bad @$$. Expensive new though. Some people have been able to get 350+ horsepower out of that thing with out forced induction, that's a riot!

Thanks, Jim

Dunno, after reading some, some racers are not powdercoating frames as sthe powder coat is flexible and wont show stress fractures as well as paint. One kick ass ride though, hope you can get some vids of it up soon.

Here is another photo of my car. I polished up the aluminum body and added the stone chip guards on the rear fenders.

JeffC: If you want some more information about the Mopar Midget engine, I can provide any information that you need. I developed this engine for Mopar as part of my job at Chrysler. This type of engine has won the USAC National Midget drivers championship in 2005 with Josh Wise, and 2006 with Jerry Coons, Jr. Coons is also leading the points championship this year w/ only two races to go.

I was wondering where you procured that engine. I was considering it for my build but I couldn't source any of the parts, avaliability was a huge problem. I chose to go with the Deman SR7 and a 1300cc Busa engine. But I still think that MME would be a killer set up. How did you guys come up with the idea and what sort of issues did you have to solve in development?

Ramtuff:

I bought the individual parts from Mopar and built the engine myself in my garage. The basic parts are available from Mopar and you order them from the parts department at any Dodge, Chrysler, or Jeep car dealer (special order from the Mopar Performance parts catalog, or you can special order from a hot rod shop like Mancini Racing, Stanton Racing, JEGS, etc):

Part Number Description
P5007636AB Engine Block w/ sleeves & Main caps
P5007065AB W9 Cylinder Head
P5007470 Rocker Arm Set
P5007468 Cam Core w/ unground lobes
P5007907 Crankshaft
P5007469 Gear Drive Set w/ Front Timing Cover
P5007722 Oil Pan Gasket
P4876757AB Head Stud Set
P4876665 Head Gasket Set
stock 340 Rear Main Oil Seal
stock 340 Damper Oil Seal
stock 5.2L Damper

The rest of the parts are from aftermarket sources:
Crane roller tappets
Manley Valves / springs / retainers
5.700" Scat Rods
Wiseco Custom Forged Pistons
Comp Cams Ground the camshaft
Moroso dry sump oil pan - custom
Barnes dry sump oil pump - 3 stage

I made several of the parts to save money:
Intake manifold - 1/2 of a V-8 w/ welding, but you could use an Kinsler, Engler, or Hilborn Midget fuel injection intake.
I made the motor plate, dry sump oil tank, modified 2.2L distributor, and modified 2.6L minivan water pump.

It would probably be less expensive to buy the complete engine used from a midget or drag racer than to build it up from parts. I sometimes see these engines for sale in National Speed Sport News or in National Dragster.

I have never dyno'd my engine, but I ran a computer simulation and came up with about 260 HP. The racing engines make about 350 - 370 HP, but I built my engine more conservatively.

I used a 1992 Dodge Dakota V-6 5-speed AX-15 manual transmission, starter, clutch, flywheel, clutch slave cylinder - since these parts bolted right up to the back of this block. This block has the same bolt pattern on the back as the small block 318/340/360/5.2L/5.9L engines.

Mopar got the idea for this engine from the sprint cars since we had been competing in the World of Outlaws and USAC Sprint Cars with an aluminum V-8 engine. Many of the other manufacturers were using the same parts for the 4 cylinder and the V-8 (i.e. cylinder head, valvtrain, pistons, header, injection 1/2 system, etc). Some of the other manufactures that were doing this at the time were: Gaerte, Ed Pink, Brayton, Chevy II, SCAT (V-4), etc.

We didn't have too many major issues in the development of this engine. We designed the block, crank, cam, gaskets, etc and made these parts. We cast the block, hand the crank forging made, billet cams, and most of the other parts are similar to, or common with the V-8 sprint car engine.

Much of the success is due to a very dedicated & talented engine builder (and his staff) - Gary Stanton at Stanton Race Engines in Nicholasville, KY.

I can send you a copy of the instruction sheet w/ a suggested bill of material for parts - I need your e-mail or mailing address.

Thanks for the interest.
