1973 Plymouth Road Runner Description

This is a true 1973 Plymouth Roadrunner, not a clone. As you can read and figure from the following, I have about $25k invested, so it is for sale at a FAIR price. I know I will not recoup all I spent, but I do not want to give it away either. When I bought it, it had a 78 truck engine, 400 cu. in., which was just a smokey pig of an engine. Remembering what happened to the cars and engines after 71/72 when I was young, with the emissions restrictions, I found and purchased a used E 440, and sent it out to Maund Motorworks for complete rebuilding.

Bottom end:

The block: spray cabinet cleaned it, magnaflux tested, and bored .030 over. New cam bearings, brass freeze plugs, stock steel crank cut .010/.010, Trimetal rod and main bearings. Factory LY connecting rods, reconditioned Keith Black KB237 pistons, cast rings for street use., Mellug M63 oil pump.

Top end:

Cast iron 906 heads, re-surfaced and magnafluxed, valve job performed with new seals. Stock valve size. Stock non-adjustable rocker and push rod assemblies. Edelbrock aluminium 4bbl intake manifold, Summit flat tappet hydraulic cam and lifter kit, # SUM-6401, advertised duration 282/293 .465/488 lift, 109 center-line 2000-5500 RPM, SA double roller timing set. and new big Holly 4 barrel. Runs on pump unleaded gas.

Rated at 475 -525 horse power. It has been stored inside for about 10 years.

At that time I also had put in a Hughes torque converter, # 37 rh 24sp 4po 2.5k. Also replaced were all the front end bushings, the brake booster, cleaned and coated the gas tank, new battery, and shocks, air shocks in the rear.Brakes were cleaned and adjusted, leaking fuel line and gasket, driver wheel cylinder replaced.

Before I bought the car, I went over it with a magnet looking for bondo, and could find none. There are tiny bits of rust at the bottom of the rear window, paint is good, but not excellent. It has always been stored inside for almost 10 years ( I have never registered it ), as work on it slowly progressed. It is now running and driving. This car is extremely clean and straight, and rust free, a shallow dent on the passenger side door. I have the trunk loaded with spare parts, but the bottom is solid.

The mileage listed on the odometer is about 15,000.

I have clear New York State title. It is a 46 year old car, so please ask questions before bidding.

I also have a spare transmission that is included.
