Yeah, a stock street HEMI was a great motor until it was time for a tune up. Expensive doesn't even begin to cover it. The biggest mistake you could make was start modifying it. Then it became a horrid mess of poor idling, transmission munching, ill mannered low rpm performance caos. The d4mn things only wanted to run at WOT. The Wedge motors were far more managable and made great torque without the huge cams and such. The guys who tried to run modified HEMIs, Ford Cammers and BOSS 429s (basically a Ford HEMI) usually were always pulled over on the side of the road with the hoods up. BUT, a well sorted race HEMI was good for 750+HP.
