Do DCOE's give low end torque comparable to the 38/38? I have also heard it is hard to get a good idle. I the top end flow of the 38/38 comparable to DCOE's? Any reccomendations? I have 9.5:1 pistons w/total seal rings, Top End performance head rebuild with 288 camshaft, Pertronix with blue coil, 4-into 1 header, I will also have 2.25 exhaust with a freeflow magnaflow muffler.TIA
