448S, theres the Rub, I do not have a 340 car to fake/clone numbers matching, so NO need for me to buy one of the GODS GIFT to the Mopar world.
If I did have a 340 car, I'd pickup a spare.
For just the $1000 340 core block I can get a lot done on a 5.9 Mag and be far ahead.
If a stock 340 makes (per Chrysler stats) 275@5,000 and 340 Tq@ 3200 RPM at the crank with no accessories and a Stock Junkyard USED 5.9 makes 288@4300 RPM and 386 Tq @ 3300 RPM with the same at the crank and no accessories I'd never bother with the 340. Its just not worth $1000 to everyone. a few but not everyone.
And that seems to rub the 340 cultists raw.
Buy what you want or need, no one is forcing you to not...
Gross figures:
340 = 275@5000 Hp and 340 ft/lb @ 3200
5.9 = 288@4300 and 386 ft/lb @ 3300. With long header 300@ 4500 and 399 ft/lbs @3400
To meet 1972 model-year emissions rules, the 340 was detuned; the compression was dropped to 8.5:1, and the intake valves were smaller. 240 gross horsepower and 290 lb-ft of torque. Still not NET rated, GROSS. Almost the same as a 1968-71 318, SHAME SHAME
NET figures:
5.2= 234@4100 and 295@3000 but this is NET and with accessories. Remember, the 318 was 235 Gross and 150 Net
