Just scored a long. Lock 6.1 and am curious if the 6.4 bottom end will work, or has anyone attempted this? My short block has a couple of spun bearings so I'm thinking that I need a couple of rods and a crank. So, why not bring this thing up to 392 the Chrysler way. Doing a 6.4 crank and rods, and forged pistons and a 10-1 compression ratio to be able to use 91 octane gas. Has anyone done the 6.4 this way, with a 6.1 block? I don't want to go out to the 426 number, or with the 4.05 crank, I don't like stretching out the stroke that far. What's the thought from those that may have gone this route.
Also, I'd like some thoughts on intake systems. This will be a high performance street driven Dart, so I'm not looking exotic, but really like the look of the Indy dual throttle body look. Open to thoughts here too.
