1990 Plymouth Laser |
|
|
|
|
WE have taken a 1990 Plymouth Laser and removed all the drive train and removed every thing from the front bumper to the rear bumper then built a Custom Pro Stock (25-1) Chrome Moly chassis to set the body on. Projected weight of the car ready to drive is 1990 pounds. (Less that a ton) |
|
We are going to use a 1967 396 which was bored +.030 over with 10.25:1 CR Speed Pro pistons. A summit .470 lift/ 260 duration hyd. cam. A Performer Intake and 750 Holley. We will build a set of Custom headers with 2-1/4 tubes. I expect to get 18+ MPG with this engine. This engine was In our 1973 GMC Crew Cab 6775 pound shop truck which got 15 MPG on the highway so with 4500 pounds less weight and a much more aerodynamic body I expect 18 MPG and low 11's in the quarter mile. This engine will be used only until we can get the 440 CID engine built. We are planning on building a 440 CID engine (427+.060) you know it is a Plymouth. Our engine will have 11.66 CR Sealed Power forged pistons. A Forged GM Crankshaft and L-88 Solid lifter cam. Because of the limited hood space we may stay with the Performer Intake but top it with a 850 CFM Holley. I only though it appropriate for a Plymouth to have a 440 inch engine. The front suspension is custom designed on the computer to give the car great handling. I utilizes custom Chrome moly upper and lower A-Arms. The upper A-Arms weight is only 2.3 pounds with ball joints. I have tried to keep the whole car as light yet strong as possible. And with the 11.75 x 1.25 rotors on the front and the rear I expect this car should stop as well as it goes. The transmission is a GM 4-speed with a 3.11 first gear. The rear end is a 9-inch Ford housing shortened to 36-inches with 3.50 gears and a Detroit Locker Diff twisting 31 spline axles wraped in a Moser Engineering 9" Ford Aluminum Case with 1/2" through bolts and using an Aluminum "Daytona" Pinion bearing support.. The rear suspension uses a custom built 4-link with a custom built watts link to locate the housing. To hold the back of the car off the large 29x18.5 Mickey Thompson tires is a set of AFCO coil over shocks. |

Because the car will be driven daily we are retaining the front windshield and will install a heater and wiper. I have built a 12.6 Gal. Aluminum Fuel Cell to fit the chassis since we are a little cramped for space. |

Since the start of this project information above may have some changes. We may usa electronic fuel injection for a couple of reasions, one reasion is I don't want to cut any holes in the hood for the carb so with EFI I can get it all under the hood. The second reason is I may add TWIN TURBOS to the car and EFI will make that much easier. The turbos will depend on money this has been a very tight budget car as of 01/28/06 the total expence so far is just over $3200.00. |
