I concur with mac op for the SRT.
Another person on a different forum has the total opposite of your story. But he properly bedded the engine, brakes, and transmission from Illinois to Niagara Falls and after 800-miles he unleashed the beast in his R/T. He was a happy camper and the fella has a 70's Baracuda.
thats encouraging...thats with an auto i'm assuming? how did he describe the increase?
what forum also, i'm always looking for more challenger forums.
