Post Hydraulic or solid cam

I'm building a 350 for my 89 camaro. It will be a weekend car drag racing during the summer. I've herd that hydraulic cams are easyer to degree in, but the solid cams seem to have a wider power range. What's the pro's and con's.

Solid lifters are better for high rpm.But if your turnin 6500 or less use the Hydrualic so you don't have to adjust um every other day.Thats what I would do anyway.
As for degreeing,I've never done it,but I think you use solid lifters to degree a hyd cam anyway so it shouldn't make a differance.

for a weekend racer I'd run the solid. they are more agressive and generaly make more power with the same specs as a hyd. you don't have to adjust valve lash but about twice a year. but run polly locks or roller rockers to make the adjustments easier.

I am thinking of running solids in mine, To adjust I believe it is just tightening the rocker studs till they tick then a quarter turn or something past (don't adjust to that spec though cuz I dunno) But I mean for having to pull your valve cover occasionaly (good to see how your valve guides and springs are holding up) Solid does sound alot better

get the cam lobe all the way down. your cam sheet should tell you the valve lash. generaly 0.025 to 0.030. put the proper size feeller guage betwen the rocker arm and the valve stem. take out the slack lock the nut and remove the guage.
