The biggest thing hurting Gen3 development/acceptance on the grassroots level at least is the cost of entry compared to brand x.

There used to be a time when you could go to a boneyard and buy a nice running 440 and 727 out of a low mileage 67 New Yorker for pretty cheap and over the course of a weekend or 2 transplant it into your grandmother's 62 Belvedere and be the terror of the town, attending hotrod class 101.

Fast forward to today, the only way you get a 5.7 for under $1k is if it's blown up. Basically now you get to start with a block and crank shaft or a block and 2 heads because the nice low mileage running one out of that 07 300C is $3K. So much for being the terror of the town in 2 weekends with your grandmothers 83 Cordoba learning anything about a Mopar other than that those LS swaps sure are cool and affordable.

So your alternative at this point if the dark side is not for you is a 5.9 Magnum. Not SBC cheap but compared to the Hemi it is and all kinds of hand me down go faster parts available as you work your way thru Hotrod 101 and beyond.
