425 Horse No Problem. Had that cam in my ERA 390 +.030 Edelbrock Performer Intake,650 DP, Edelbrock heads milled .040, 76cc to 68cc CR 10.12:1 353 rear, Comp roller rockers GREAT SOUND AT IDLE. Just make sure to use end supports on your rocker arm shafts. The added spring pressure for the solids will cause a problem. I never beat on the motor still broke two shafts, wasn't just me either have friends with 427's and 428's same thing. Before I sold the car had new shafts and end supports installed, didn't want the new owner to get that sinking feeling.
