edelbrock roller cam in a 454?

[shipma2]

i think my 454 has a rv cam in it, would an edelbrock roller cam be a big improvement ? give it any more tourqe or power?

I have a bone stock early 454 with stock 781 heads. It breathes good upstairs and downstairs but nothing fancy. I went with a full roller valvetrain. Not big though....only a 270HR with 270/276 and .510 of lift. Click on my video links in my signature to see how she does. Granted, it is a TH400 with 3K of stall and 4.20 gears. It sends it down the road okay! lol
