zgeezer Posted September 21, 2002 Share Posted September 21, 2002 I can't seem to find a definitive answer to the C/R of 350 ci LT1 with iron heads. Some sources say 10:1; one states 10.45:1 and others 10.5:1. My real question is whether the iron heads are the same as the F body aluminum castings. I know the lt4s have substantial diferences. Two sources have stated that the later iron heads (1994-1997) flow better than the aluminum heads. Does anyone out there have solid information? Am I reading too many Impala SS posting? Help? gw Quote Link to comment Share on other sites More sharing options...
