firestone said:As the cam rotates, a tappet follows the outside of the cam lobe. This tappet is raised up by the lobe and pushes against the pushrod. The tappet can have a flat face that glides on a very thin layer of oil on top of the cam, or it can have a roller which rolls instead of sliding. This rolling reduces friction and allows for a steeper ramp of the cam profile. The steeper ramp in itsself increases performance by reducing the time spent at lower lift. Also, it allows for greater overall lift of the cam. A hydraulic cam has a small spring in it and is also filled with oil. This acts like a shock absorber for the cam and valve train. The benefit is that you do not have to readjust your cam once you set it. The bad side is that you dont have the valve control that you do with a solid lifter with no spring or fluid inside. Because of this the solid tappet will make more power than the hydraulic tappet, but you have to adjust them fairly often. Hydraulic and solid flat tappets are pretty cheap, you can get a cam and lifters for $150-$200. Hydraulic and solid roller cams make more hp, and provide for a more relyable system as far as longevity goes, but cost around $600-$700 for the cam and lifters.
I take note! Though, $1500 Canadian or Americanfirestone said:For 1200 you can get a nice set of heads, but if you could swing another $300 and get the new eliminator AFR street 195's that is what I would recommend. These heads along wtih a properly matched hyd roller cam would easily get you 500-550 hp.
Here are the heads:
I would recommend something like the comp XR288HR (236 242 @.050 .520 .540 lift 110 lsa along with a set of 1.6 rockers which would take the intake lift to .550 and exhaust to .570) I would also recommend the edelbrock performer RPM intake. This should pull to around 6000 RPM, and make 500-550 hp.
