I have a Briggs and Stratton Animal
Engine. This motor is great! I have a 310 cam, chrome Molly push rods, Pvl 12’000 rev limiter coil, Billet Rod, 1.2 Roller Rockers(Which I haven’t installed yet) and a Billet FlyWheel( Which I haven’t installed yet). This motor is great and most definitely reliable. As of right now I have a Level 10 Attack series big valve head installed that I got from JRPW racing about 2 weeks ago. It has a 3 angle port and polish job on it. The level 10 head has 42lbs springs on it. I can either sell it with the level 10 head on it or I can reinstall the stock head back on it. The stock head has 36lbs springs on it. So basically the price difference is gonna depend on which head you want. I also have 2 exhaust pipes for it. One is used shown in the picture and one is brand new. I had a PWK 24mm carb installed from EC Carburetors but being that I put a better flowing head on I had to upgrade to a 28mm Mikuni flat slide car from OMB warehouse. I have receipts for everything I’ve done to this motor. With the level 10 head on it I’m asking 1000 dollars and with the stock head installed I’m asking 600 dollars. Feel free to ask me any questions or for more pics/ videos. Thanks
