![]() Hey, this is briefly discussed at Mustang Works, Articals/Powertrain/Cylinder Head Science.
"Alum. Vs. Cast Iron Given a 9:1 or 10:1 compression ratio (static) an Iron Cylinder will make more horsepower than an Aluminum head, due to the fact that it retains heat (power/energy) more efficiently. However, Aluminum is lighter, easier to work with (and cheaper to produce), and more easily repaired. In addition, Aluminum is more resistant to detonation under high compression, nitrous or boost situations." http://www.mustangworks.com/articles...adScience.html ------------------------------- '79 Mustang Coup 4" Cowl Weld wheels (15x6;15x8) Stock 5.8L C4 w/ shift kit 1.5" MAC full length headers Holley 750 CFM Edelbrock intake 2.5" Off road H-pipe, 2-chamber Flowmasters 8.8" Rear end w/ 3.55 gears (Now that's more like it!!) ![]() Front: 225/60/15 Rear: 255/60/15 Eagle GT II 14 x 4” K&N air filter (getting the Xtreme setup soon) ![]() "Red, thou art my companion.
