solid and solid roller cams

[sharkey]

does anyone have a solid lifter or solid roller cam in their 660??? im just starting with building my motor, and am still looking at cam choices. i know crower makes roller cams, and several other companies make solid lifter cams. i know there is more power to be had with a solid or solid roller, but matinance becomes an issue.

how often do you need to set valves on one of these for a street motor??? this is my main concers, as its not as easy as popping the valve covers off in my car (86 z24), the upper and middle plenum must come off, making setting valves a several hour job.

I do and check them every so often, but with an all roller valve train, they actually haven't needed adjusting since the motor was assembled, so it isn't that big a deal.

interesting. how many miles on the car since it was put together???

Just wondering, why not go with a hyd roller cam setup? then there is no adjusting?

[TurboZ24]

um. Last time I had it apart was in the last cam change, so like March of 2001? That's the last time I had to set the lash. I don't drive a lot, but enough.

IF you went with a hydraulic roller setup, you would have to use the 3100/3400 retainers/lifters. You are also still technically limited to a max of 6800 rpm or so. If I was going to spend the amount of money for a billet roller, I would want the most I could get out of the car.

correct me if im wrong
but solid lifter cams need adjustment made with every oil change

[TurboZ24]

There is a difference between checking it and actually having to adjust it. I've never actually had to adjust it, since it's remained within spec.

Yea you do not have to adjust it all the time. You can do a quick check with a feeler guage and would not need to remove the intake. But would need to remove a couple things on the engine.

You cannot just stick a Hyd roller setup on a Gen I or II block. They are not a priority main feed oiling system and will not support hyd roller lifters.

on my car i cant get the rear valve cover off unless i remove the upper and middle plenum, and power steering pump, so its a bit of a chore. took me 3 1.2 hours to change both valve cover gaskets.

[TurboZ24]

I have to pull the plenium, fuel rail, DIS module, and alternator bracket, but that's not too bad to access the covers.

[geoffinbc]

Really? I swear to go we pulled off the rear valve cover on my buddies 3.1L with the plenum on. What engine do you have?

[sharkey]

thats is on a 3.1l gen 2 motor with the gen 2 intake. on a gen 1 motor, the valve covers are a lot taller and the intake sits right over them. its next to impossible to get them off without removing the plenum, and even then, you wouldnt hardley be able to adjust the valves.
