Drive Train Upgrade Suggestions

Appreciated the input and not sure if my attempted youtube video post to the group was visible to you. If not, would appreciate your thoughts on this /6 upgrade end-state versus the V8 route -- https://youtu.be/4zHxzHEs14k This seems like an interesting optimized 225 that appears pretty amazing as well. Would need to assess costs of this option that would require a full tear down and rebuild of the engine + the weber carbs versus a new drive train as-is.

cool little motor but 282hp and 291tq? ill bet there is a ton of money in that thing to get those numbers. mild V8 can easily surpass that snd probably cost half to build.
