6.2 hellcat crate motor
But you gotta admit, that 6.2 was designed to be daily driver in 100* heat and warranty friendly. Not to say the average joe can't build that, but someone else has already done thousands of hours of R&D and testing to be sure...
I totally agree. If I was building something that hasn't been done much, I would definitely consider a crate like the 6.2. The amount of engineering to make it last is huge. You get a ton of built in protection in areas Joe average wouldn't even know to look at. Proper coolant flow for 700 hp? A 50 percent strength margin for warranty? Pistons that will survive a standing mile run cause YOU KNOW somebody will try it, and the factory had to anyway for testing.
Gaskets that will live? Lots to think about. Of course you can also spend $20,000 plus and build your own ( me, 528 BB race motor), then repair what ever goes wrong. BTDT. Even supposed absolute best valve train parts gave me fits, till I figured out how to make em live. Then the factory rep says, ya, we changed to something like that!!!
But in the end, if you go with a crate and factory electronics, it ought to be bullet proof and maintenance free for the most part, provided your fuel supply and cooling are built right
I wouldn't fault a guy for going either way though. The build your own route is a lot of knowledge to gain, if you stick it out. The crate, peace of mind. Owners choice!
