Apparently, the 383 4bbl is only putting out 10 more horses then a small-block 340. Said to be only 285HP.. wrong.. definitely 325+.. only difference is in the torque.. i think they are putting out about 375 ft lb... but really just look it up on google. you will find everything you need to now.

1970 was the last year for high compression , 335 HP and 425 ft.lbs torque was the MAGNUM 383 or ROAD RUNNER engine . the standard 4bbl 383 was 300 HP with the same torque425 ftlbs . About the only way to tell a magnum from a 3oo Horse motor is to read the stamping by the water pump flange or take off the valve covers and check for red springs (MAGNUM )

actually 1971 was the last year for direct connection (now MOPAR) to have high compression. my first car was a '71 charger (383, 4bbl) and the guy I bought it from still had the original window sticker! it said that it was 335 hp but I forget what the torque was rated at. not trying to be a know it all jerk, just giving some info that I have to give. MOPAR ROCKS! take care guys

the 383 put out a t=rated 335 that was actually up to 375 with ramair.

I have a 1972 cuda with a 340 automatic what the horse power for that car I know the older 340 had more horsepower then the one I have

I have a 1970 Barracuda. I race it for 10 yrs.. It runs 15.10. quarter mile. Varys in some location. Maybe 15.25 to 15.30. It's been very consinsten. So the guy on the top of the page is very close. 330 hp. If the weights. Make a big difference.. Next month. I let you know how my 66 383 runs with the 2. 4 barrels. My buddy. Going to Dyno it..
