No not that car... my Rampage is 10.4 compression
with iron heads
Wow, you had me going there... and in the back of my mind I was thinking "when did they ever make a W9 in iron, OK... don't know everything, maybe they did."
There is so much information and misinformation out there on this topic. I read one place where they say you can go up 1 full point when going from iron to alum w/ no drawback, then I read that DCR is the key, and it makes no difference if the head is iron or not. Then there are folks swearing they run higher than the "recommended" 8.3 DRC because they have better heads and flat top pistons with good quench. The number of opinions on the topic seems infinite. And then add in whose DCR calculation method is correct, and what number to actual use, and, then, of course if it is a solid lifter cam it is different and lash comes into play. Of course altitude here is 675 feet above sea level... that matters also. Just in case... car is painted dark green.

Well I agree with the full point of comp with alum
heads.. also your altitude is low and one other thing..
if you keep the engine cooler it helps also... JMO
but 11.25 and alum head 625 altitude on 93.. I'd run it
