I believe it was 230 horse.
The 318 generaly gets any were from 225 to 235. That is if it is bone stock.
They were rated at 230 hp
230 hp (318 2v) 260 hp (318 4v) 230 hp (318 2v) 260 hp (318 4v)
Right at 170 HP with stock carb
170 hp 260tqe
The stock 400 Big Block was actually a 402 and they had 2 engines in 1972, one had 210 HP and the other had 240 HP.
Around 150 HP depending on the condition.
There is about 310 in a Z28 I've personally seen dynos of 318 Rear Wheel Hp. Which would equate to about 340-350 flywheel hp. Yes this was stock.
318 =160 hp 360 =180 hp 400 =200 hp 383 =258 hp 440 =235 hp all where found in dodge trucks from 1972 to 1980
