I'm running Crane 99895 springs with Crane rollers on a 139641 cam. The engines have about 100 hours on them and based on this thread I was thinking I may replace the lifters with Isky or Jesel. Should I just bite the bullet and put a new cam in, I could probably use a little more cam, do the lifters and springs. Might as well to do the rockers too, they're Crane golds. I spin the up to 5600 rather routinely.

The 280 aka 26 Velocity is a great runner. It is however a drivers boat and a good driver that is able to keep the boat on the pad can get more out of it then someone that just sits there.

Jack, thanks for your help, nice to have you back!!!

Vel Mark thats awwesome! How many cubes? And how big are those heads? My 502 stock block Brodix320 heads and a 741 with 7# ran 94 and then the hatch ejected and I stopped! The Velocity is the hull I wanted, but have an Eliminator 25. Any details would be great. Thanks Greg

I would be looking at springs as a bare minimum. I had the comp 929 springs and they are down about 15lbs at seat from new. I am still not sure why my lifter broke but I have to agree with Budah on springs. If I go back with hyd roller it will have the best springs I can get. All the other lifters look great and no binding I can find to cause problem.
