If you want to make it easy way, just like millions other then build V8. If you want something intresting and different, then slant six. I'm building slant.
Not many Mopar V8 Turbo Muscle Cars out there.... and there is nothing easy about shoving Twins under a stock hooded, inner fenderwell in tact A Body Mopar either, Heck even a Single Turbo is a PITA with all the plumbing. To say it is easy is not a true at all.
