While I have not used them, I have been very impressed with QMP:

QMP Racing Engines
At Quarter Mile Performance, all services we offer are done under one roof at our shop in Chatsworth, Southern California. Everything is done inhouse, no service is ever outsourced. We can do anything from basic surfacing to machining a custom piston from a blank forging.


We do everything from building your engine to our complete, turn key QMP Racing Engines. Whether you're racing in Heads Up Fastest Street Car (Nitrous/Turbo/Blower/NA), NHRA/IHRA Comp & Super Stock, Marine, Drag Boat, Street & Strip, we have the proven combinations to get you to the winners circle. All complete QMP Racing Engines are dyno'd with true HP numbers. Tell us how fast you want to go, and we will make it happen. Check out the finished vehicles page. Complete engines are now for sale.
