How high in the rpm can you take the stock 305 bottom end. My heads can handle it. Or rather. How many times can I take it to 6500 before connecting rod leaves the block.

(Max piston speed / Stroke) * 6 = Max safe RPM.

I probably wouldn't go higher than 6500rpm on a 305. Then again, if you do, it'll accelerate the progress towards not having a 305 so could be a win either way.
