I have a 440 from my 74 rr gtx its all stock never been played around , as i see in the books they say it as a weak 8.2:1 compression , i have no clue whats the cam size on that thing , thermoquad carb , must be around 800 cfm too , and does the heads have the same valves size than the other 440 heads ? Never played with big blocks , always been around the 318 340 and 360 , so i need a bit of info thx a lot guys
 
I thought there was a sticky in the tech archive with cam specs.....
 
As long as the heads haven't been swapped the valves will be the same as other 440's I 2.08 E 1.74. But as far as cam specs, more than likely not much oomph above 5000. But don't think with the low compression that it can't make good power. Search member IQ52, he did a low compression build.
