Today we are taking a classic 375 hp 440 mopar big block, and seeing how much power the legendary engine actually makes. We are using the California Auto Workz chassis dyno for all this testing. I hope these numbers dont break the hearts of anyone!<br /><br />Its dyno day for the 1970 dodge challenger rt! This car is sporting an original 440 HP from 1970. The engine has been rebuilt to factory specs with only a few minor changes. We will be running this car on the California Auto Workz dyno in Hemet California. Carburetion is controlled by a Proform 750 mechanical secondary, race series carburetor sitting on top of a dual plane aluminum intake. Exhaust is handled by a set of 1-7/8 long tube headers ran into dual 2.5 exhaust tied together with an xpipe and then entering into a set of chambered mufflers. The transmission is a 727 automatic and the rear end is a mopar 8-3/4 3.23 sure grip rear end, both original units. Today we will find out what a 440 mopar big block ACTUALLY does on a real dyno. This aint no motorhome 440, I hope it makes good power but we'll see!<br /><br />#mopar #challenger #dynoday<br />...<br /><a href="https://www.youtube.com/watch?v=ztrIAMQG6Xw" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=ztrIAMQG6Xw</a>
