serious question, my goal is a 600+ hp challenger. i plan to buy one used, and keep cost as low as possible. that being said, i would greatly appreciate some suggestions and advice. should i get a r/t or a srt? does it matter? is there any cheaper alternative to build a 426 other than buying the 15k crate engine? which would be better anyways, a crate engine, or just upgradeing the parts in the stock 6.1/5.7/6.4? i want something i can drive to work everyday, but yet not be scared to take on a zl1 or gt500 at a stop light or the track. im getting to the point where there is so many options im getting over whelmed as to what are the better options.
