I used to spin 5200 with mine.. and it ended up with broken valve springs and a cracked valve.. So if it has stock springs keep it under 5k. Thats what they told me at the time. With new one piece SS valves and new springs.. i wound it up...
Ended up with a 513" motor that would turn 6300... but they don't last long at that level.. *S*
