1976 Plymouth Valiant Reviews, Pricing & Specs

This is the car that dreams are made of. I got this car from a neighbor that was going to move and he didnt want to take it. it had a slant-6 that made a whopping 85 horsepower with 61foot pounds of torque. it is a 1 of 5 car because of the white stripe. it is the last year they made the valiant and it is loaded. here is what i have planned for that little car. I want a 318 block to start with. 318 to 402 Stroker -------------------------------------------------------------------------------- 318 to a 402 LA Block Stroker, using the Edelbrock RPM package Here is a thread that spanned a few months during the build. This will cover all the issues I encountered with this build. Once I got theValiant home, Here is what we started with. With the engine out I had grand visions of a massive 416 LA Stroker (ya I know...why didn't you build a Big Block??? Everybody builds Big Blocks! I want something different), first step take it to the machine shop and see what is good. Fortunately, the block, crank and heads were all good. The crank and heads I managed to sell to the machine shop as cores. The machine shop did ultra sound to determine the cylinder thickness after the Magnafluxing and block cleaning. After a discussion with the shop we agreed on a 4.00 bore as reasonable, should be plenty of cylinder wall for cooling. What they did was offset bore the cylinders to ensure uniform thickness around the cylinder. Here is the block freshened up a bit. Piston choice was Diamond Forged Pistons P/N 51401 Rods were Forged Eagle H beams P/N CRS6123C3D Once the block was bored, we added a Mopar Performance Forged crank P/N P5007252, the block had to be clearanced, here is a picture of a cylinder that has been clearanced. One of the big headaches was the bottom end Oil pan. Turns out the Main caps on the 73 LA Block were low profile. The Windage tray would not work with these caps. I ended up with Mildon P/N 32230 for a windage tray, with Milidon windage tray studs P/N MIL 81167 (Ford studs) that had to be machined to work. The Oil Pan was a Mildon P/N 30935. We discussed the Cam and Head choice, and I decided to go with the Edelbrock Performer RPM line, and Comp Cams Roller rockers. Heads Edelbrock P/N 60779 Intake Edelbrock P/N 7576 Roller Rocker Comp Cams COM132216 Heads on Heads and Comp Cams Roller Rockers The Intake is an Edelbrock Performer RPM Air Gap. Carb is a Performer 800 CFM with electric choke. Here are the pics of the Motor just about done and ready for dyno. Dyno Time Here is a movie of the motor on the dyno Right Click save as, else click the link and it should stream http://www.retrorelics.net/jim/FilesDL/Dyno402DL.wmv Here are the results Quick lessons learned... 1. Mail Order the parts (paid no state tax on the mail order items that alone is worth a few hundred bucks). 2. Research the parts and hunt the best prices, some parts I did, some parts I let the shop get. After seeing their mark up, I will provide all the parts my next build. __________________ 1999 C5 A-4 1 of 245 Nassua Blue 99 Vert's, 3.15 Rear, AR LT Headers, Borla Stingers, LS6 Intake, Shaner Ported TB, Blackwing, 100 Shot Dry, Nitrous Outlet Wet Plate @ 100 shot, Hard-lined by Vin @ 860 Performance, Hoses and 42 # Injectors by HSW, Racetronics Fuel System, Bottle Heater/Opener/LC1 WB/Gauges by DynoTune, EFI Live Scan/Tune V2 from GLMS Custom Nitrous Panel.
