70 cast iron intake on a healthy 455 street motor
i purchased a used 455 +060, that i am going to put in my 69 firebird. I do not have all the specs, but by the dial indicator it has about a 580 net lift ultradyne street solid roller cam, # 15 heads that have had screw in studs and 1.65 sharpe rockers on it. I have had it running on my stand it its a snotty healthy little motor. zero decked, trws, main studs, been done failry well especially for when it was originally built in early 2000s. Currently has a performer rpm holley on it, but... i would like to keep it stock looking, and am considering a 69 intake and qjet, or a 69 intake and an adapter and a holley. I know everyone hates on the rpms any way, but aside from the weight savings, what am i giving up?
should be mostly street, about 450 hp lets say and a three pedal car with 323s in it.
