What if my cam is alredy pretty agressive. With the solid lifter it would be less agreesive ONLY because of the added lash? But if the hydro lifters dont really pump up isnt it really a wash? But you can still have the bennefits of what a solid lifter provides.
Obviously I am giving this thought for my car.
220 in, 228 exh dur and .589" lift
So I loose .020" lift but now I know the valve springs will not fight the plungers and in essence will make this cam closer to the profile.
Can you put down an example. you can use my cam spec for discussion.
It kind of sounds like you are looking for an inexpensive way to increase rpm potential. There are a few other things you need to consider first.
1) You don't have anywhere near enough valve spring to run higher rpm. You'll have to change valve springs, possibly valve spring retainers, cups, etc.
2) Your cam doesn't have the proper valve timing for high rpm use. It's a mild cam that peaks power at about 6000rpm, can hold power for maybe 600-800rpm beyond that but torque will be falling off quickly by then no matter what.
3) Your rocker arms aren't up to the job of higher spring pressures, and they are not adjustable anyway. You'd need adjustable valvetrain, and you need something bigger than 8mm bolts to hold it all together.
4) Heads have to come off to install solid roller lifters.
5) You should upgrade to a double roller timing chain, which means cam might as well come out at the same time and get something better suited to higher rpm.
Count on about $1500 in parts alone to upgrade to a solid roller setup, then add machining to the cylinder heads, etc....
