Since we are sitting here speculating until KV gives us more info...here are some observations I made from their CAD model.
The cases appear to be completely custom, the starter location seems to be similar to a 66E like the TeamScream engines but the flywheel cover bolt pattern is completely different from both the 66E and 62T engines.
The exhaust port and manifold flange seem to be lower in respect to crank centerline, having no idea if this uses 62t cranks or 66e (or other?) it would seem that a custom manifold would be required to run the existing exhaust systems so as not to hit the bedplate/engine mounts and the exhaust port runner will have a much steeper angle.
The carb mounting location is much higher, the model looks odd in that area like the carb and manifold are one piece which I would assume is not the case, likely just lazy modeling BUT will standard height SBNs fit? Off the shelf flame arrestors definitely don't look like they will fit under the hood.
