Advice: Solid Roller or Hydraulic Roller for street car

If the OP is trying to decide between a solid vs hydraulic roller cam to squeeze every last ounce of power out of a 318 for a street car, he's better off spending a couple hundred bucks on a good 5.9 roller core to begin with. Then he'll at least have an extra 40 cubes to help take advantage of those trickflow heads.

I hate to be that guy but I just don't see the logic in bolting on a set of trickflow heads and installing a solid roller cam into a 318 in order to maximize power - unless he just really wants to keep the 318.

He said "...I’m not trying to break any track records but I want the project to have worthwhile gains for the time and money spent." Has he looked up the cost what of a roller cam and a good set retrofit roller lifters run these days? Starting with a 5.9 will be much more cost-effective.
