Crate 360 vs DIY Built

See the other posts on crate engines...
They are a crapshoot as far as I'm concerned. There is no way a crate engine can be as good as a properly matched, custom built engine can be for what you want. You have a goal - would you rather fit a compromise engine in there or have a qualified builder talk to you and maximize the result to your goal?
You're in Ca - talk to OU812 here. That's Brian at Indio Motor machine. A Mopar guy and sharp, and not accross the country in terms of shipping.
