[QUOTE="Quick Strike, post: 16423921, member: 11920"] I don't think you would pick up much going to GT500 cams. Basically you would have 12* duration on the intake and 2* more on the exhaust. Then there is .068" more lift at the intake valve and .058" more lift on the exhaust. A new set is going to be at least $1000 for maybe 20 HP. A used set may be found, but it would need to measures and reviewed for damage. Then where are you if it is damaged? The second issue here is your desire to bring the compression up to 9.5:1 static compression. Stock cams installed in their stock configuration were made to be used with the lower stock compression and have a dynanic, or cranking compression, that is optimal for 91-93 octane fuel. Raising the static compression while leaving the cams in their stock location will raise the dynamic compression as well. The fuel becomes more detonation prone under these conditions as a result (unless higher octane fuel like E85 is used). I would use cams that would work better in the combination if you really want to go with higher static compression. Something like [URL='https://www.compcams.com/xtreme-energy-r-s-charged-n2o-222-224-hydraulic-roller-cams-ford-4-6-5-4-5-8-modular-4-v.html'][color=#003366]Comps XE258BH-116[/color][/URL] are made for SC engines and have much longer durations. That makes them better for higher static compression and keeps the dynamic compression in an optimal range. [/QUOTE]
