Mullins Race Engines 415 – 13 Degree MOD Engine

Mullins Race Engines 415 – 13 Degree MOD Engine


415 – 13° MOD ENGINES
We designed the 13 degree engine for one thing in mind… Basically a “more powerful” engine option over our open 23 degree. If your a team that consistently races on bigger tracks and feel your at a power disadvantage with the 23, this is a perfect option for you. We designed the head around dirt modified racing so the intake port cross sectional area resembles the Outlaw head. We did this so it had the same drivability characteristics. These engines are smooth to drive but I will say that more torque and power is harder to get tractioned up over less torque and power.
Unfortunately these engines have gotten more expensive, Edelbrock quit making the cast manifold so we have to make a billet one. The billet manifold is a lot nicer and lighter but it does add to the expense of this engine. We really only build this engine with the higher end upgrades. This only makes sense with the power level it makes and knowing that guys are buying it to run on bigger tracks.
