Thread: Hydraulic verses solid cams SBC

Tweet

Can you run a solid cam with more duration on the street than a hydraulic cam

for example most hydraulic cams run good on the street with 225 - 230 degrees duration and around .480 lift.

Can you get away with a solid lifter camshaft at 250 - 260 degrees duration around .500 lift?

I'm only asking this question because I'm curious to why you can run more duration with a solid lifter cam on the street and get better horsepower.

Here, read "Secret #1", that might help.

specifically the old l46 hydraulic grind and the lt1 mechanical. These grinds are different from the ones supplied at the start of the thread which were a competition cam (hydraulic) and a lunati cam (mechanical).

Read the article on H Cranes cam secrets on acceleration ramps etc and will be heading out to the garage to degree several cams toget my head arond it.
