RHS 410 update...

So in the CC build what all parts could you keep from the stock engine? Trying to figure out for myself just how low buck I think I could make it. I understand I might miss out on some power, but just curious. Can you reuse a stock oil pan or are there clearance issues with the stroker or something? Similarly, I assume you could reuse the stock ignition?

If you use a stock oil pan, make sure you use a windage tray. Stock ignition would be fine, just use a good coil.
You can literally use the stock top end, stock rods and a KB hyperutectic piston. This would be a very mild build but would add considerable TQ.
You could then use a larger cam like [email protected] to help move that power up the rpm range so it's not done by 4000rpm.
But you make like it done by then....LOL! I would not use a cam smaller than [email protected] though...even with really low compression.
