  • 1966 Plymouth Valiant 100 sedan, 56,000 original miles.

    1972 340, 650 Holley DP, Super sucker 1 inch carb spacer, Mopar M-1 single plane intake, 505 Isky cam, Rhoads lifters, Comp Cams push rods, Comp Cams aluminum roller rockers, stock 340 heads 2.02/1.60 Milodon valves, 1970 340 steel crank, stock rods, .30 speed Pro forged pistons. The rotating assembly has been balanced. Moroso deep oil pan, HV oil pump, stock windage tray, Hooker Super Comp fenderwall headers, 2 1/2 dual exhaust with flowmasters. Mopar Performance distributor, MSD 6al ignition box and Blaster 2 coil, Accel 8.8 wires and NGK plugs.

    Cooling system is a stock 273 radiator rebuilt with a "High Flow" efficency 2 row core, stock metal fan shroud and 4 blade fan, Flow Kooler water pump and 160 degree high flow stat, also run the stock pullies. I am also running a vintage "Cool Can" for the carb.

    1966 4-speed A833 trans, 3.09:1 first gear, Centerforce II clutch and pressure plate, stock 10.5 flywheel, had 1969 Dart Hurst shifter but recently installed a 71-74 B-body bench seat Pistol Grip shifter, 10.5 conversion kit from Brewers Performance.

    Rear is an 8 3/4 with large bolt pattern Yukon axles, green bearings, 4.10 Richmond gears, clutch sure-grip, Mopar super stock leaf springs and drag shocks, Mopar Performance adjustable snubber.

    Front end has 1973 Duster disc brake spindles, tubular upper control arms, 3-way adjustable drag shocks and a fat aftermarket sway bar. Original k-frame, Schumacher engine mounts and Torq strap.

    Front rims are American Racing 15x4 Torq thrusts with 5.60-15 tires, rear is stock 15x6 steel rims with bald 255/60R15 tires.

    I ran the car on a chassis dyno on 5/31/08 and it made 297.9 hp at the rear wheels. Made some 1/4 mile passes on street tires, best time was a 13.41 @105 mph, tires spinning in every gear. Now I need to get some slicks!:toothy10:

    I now have some 255/60R15 Mickey Thompson Street ET drag radials to throw on, that should help my quarter mile time a bit! :-D

    Next step is to install a dual quad Weiand tunnel ram that I have, I am thinking this 340 will like it!

    Hello 66340SEDAN,

    I happened upon your post on the details of your 66 Valiant. I'm trying to estimate hood clearance and was wondering if you had the height measurements from the 340 block for your Intake, Carb Spacer, Carb & Air Filter? Also how much above your hood is your air filter? This information will help me figure out a few things.

    Thank you for the help!!

    PS. Very cool Valiant you have!!

    The epitome of what a bad ass '66 Valiant should be. Old school. Has to be fast!!

    I have always admired your Valiant, but this is the first time I viewed your album (not sure what took me so long). Reading the specs, hp, times etc, your little Mopar is BIG-TIME COOL.
