Speedomotive engines

I just want to warn everyone to stay away from this company......I had speedomotive build me a 520 cid Mopar and the engine failed after 51 miles. The company charged me for Comp lifters....and put the cheap 440 source lifters in resulting in the engine failure. Taking no responsibilty....George and the Speedomotive have done nothing for me to help with the $5000 bill to repair engine. PLEASE STAY AWAY FORM THIS COMPANY....
