Mopar Magnum
there were 3 different 360 crate motors, 300 hp 320 hp and advertised 380 hp which was really 397 at the crank,, looks like u have the 380/397 hp motor,,, 30 percent of 397 is 119 that puts u at 278 hp at the wheels on iur car on that dyno pretty good,,, i highly doubt its a 408 the 360 are no longer available thru mopar performace as a crat motor as far as i know,,, depending on what cam you have,, for the street you may find a dual plane intake will be better on the street,,, a set of GOOD headers will wake it up and some carb tuning,, but to tune the carb you really need to have a starting point,, cam,,,rear gear,,,tire size,,comperssion, etc,,not that it cant be done wiht out some of that info just a better starting point,, cheaper in the long run if you have that info,, also what the convertor is,, and what you realisticly really plan do to with the car as far as driving it,,, street /strip or mostly street,,, but you have a great motor there no need to go in side it,,, just a set of headers maybe a convertor,,good exhaust and mufflers,, and a nice rear gear and tire combo,,, nice find
