I need to know more about the engine I have in my 63 SF. How much can I learn about the engine without total taking it apart? I'm going to try to measure current cam lift using a dial indicator, If I am correct if I measure on the lifter I well need to multiply by 1.5 to get the actual lift. Is there any way to get an estimate of compression ratio without removing a head? Is there anything else I should look for? I don't know if it has hardened valve seats, I've read that is not necessary and others say it is a must. If I pull a head I'll have it checked. Any comments would be appreciated.
