1. Stay around 10:1 and ya wont have a problem running pump gas. Most people think more is better but its just not true. If ya really want more grunt work with your rear gear ratios. Lets face it most daily drivers dont get to go much above 100 mph so if ya build it to hall ass 0-60or 70 ya dont need all that cam lope and hp all be it sounds fantastic ya dont need it.
2. good video. There are also calculators available if you know all your specs. SW Iowa by chance?
3. Why didnt you can advance your cam to change power band down low to suit the truck better .
4. Never heard of "dynamic compression ratio" - only static. That's all anyone ever talks about.
5. Hey thunderhead, I'm building up a Mopar 440 to a 507 with a .528 purple shaft cam and I'm looking to go to a 7.9 dynamic with the cam advanced 3* for seating to happen at (ivc) 69* but that makes my compression 12.2:1 will this run on pump gas? I'll go on your word
