305 = 6000 rpm?

I know a stock bottom end of a 350 will spin to 5800 all day. Will the stock 305 do the same? Now it shifts at 4500, seems like there should be alot more. The stroke is the same (305 and 350), but are the journals different? Would that really matter?

I'm sure it doesn't matter if its a 305 or a 350. The bottom end isn't what you have to worry about, its the valves and springs. If you have stock springs, I wouldn't go past 5500. I rap my 350 with LT4 HOT Cam springs above 6000 whenever I race.
