347 Pros/Cons

The lifter is a component of the valvetrain and is very related to the cam chosen. The hydraulic lifter is more streetable where as the solid lifter does require more maintenance but has more potential. Given proper maintenance there is no reason a solid lifter can't spin to 10k, but this is all very specific to the cam.

Right...and a blower cam likely wouldn't benefit from solid lifters. I just think solid lifters when i think of old Windsors. Probably the best route would be a roller conversion and a small base circle cam. You wouldn't need tons of cam to make big power with a blower and 400+ cubes.

The small base circle cams really limit the potential, even custom...... There are benefits to a solid roller, even with a mild blower or turbo cam.

It is all about the "COMBO", to make good power and torque and be reliable you have to put the right parts i the mix. If you cant make 600hp with a 400" motor and some boost you have something seriously wrong.

Like mwood stated above it starts with your goal, what you want to do with the car and BUDGET, once a budget it defined you or your builder can see what parts work best for what you are trying to do. It is cheaper to build a aftermarket block up front then build 2 stock blocks... 600HP doesn't belong in a stock block.
