After a day of research i come a conclusion that I need to improve the air flow and efficiency of the engine. Some port work and new rocker arms.
First I need to get the bottom end to handle the extra horsepower than work on the flow of the air.

Brent I would like to talk to you about of a plan of attack. To get me where I want to be with this engine.

I would like to start gathering parts to up grade my 428 engine in a cobra replica. Little about the engine  is bored 30 and running 10.5 compression. Cam spec HYD  310 cam lift 542 valve lift  270 Dur .221 050 Dur  lobe center is 108.Heads are Survial FElony head matched port to a Edelbrock rpm manifold with a 750 Holley for carb. Stock adjustable rocker arms with new shaft and end stands. The bottom end is stock except the arp rod bolts was installed. Transmission is TKX and 3:31 rear gears. Dyno 473 horsepower and 501 toque.

My question if I up grade the rocker arms and cam  would I gain  more than 50 or more horsepower gain with these changes.
