'68 400 H.O. compression and $ difference
Hey all!
I am corresponding about a 1968 Firebird 400 H.O.(I'm told). It is supposed to be correct and original. I have 2 questions. 1) what is the compression ratio on this engine? Just curious about buying fuel. I know someone who has a Firebird 400 that is 10.5:1 and that car doesn't run worth a darn on pump gas(pinging and vapor lock). Also, what is the difference in value between a base 400 car and a 400 H.O.?
