Quote: like example i would like a cam with nice valve lift but in the future i would also like to use forced induction will that cam work why or why not?
There is not a one size fits all, forced induction guys are having best success with an almost stock grind because the blow dryer is doing all the work of filling the cylinder. The same cam on an NA car would probably be best matched to a stock 1 barrel car, or a super six car.
There are a number of cam books out there that you can read and get a theorhetical idea of what effects changes can have: narrow vs. tight LSA, more or less duration, advancing the cam vs. retarding it...
It is very tough to specifically know what is going to happen unless you've done a lot of 'building' (for self or others).
A nice lift can mean things to different people...
NA vs. boost are two completely differing disciplines, with boost the hair dryer is increasing the volumetric efficiency of the engine by forcing the fuel air charge into the cylinder. With NA the intake is lazy relying on rpm/atmospheric pressure/intake style/the cam overlap event to help pull the intake charge into the cylinder before the exhaust valve closes, and your exhaust system-headers promote scavenging where as a normal exhaust manifold may not...
If you have to break it down for the noob, NA slant six building has a couple of common paths to follow:
1) Low compression, RV or short duration cam- short overlap event allows cylinder to build pressure sooner, has good idle and you get good lower rpm driveability and torque.
2) High Compression, long duration cam - long overlap event allows both valves to remain open longer to promote scavenging (if using headers), but also are open longer causing cylinder pressure to bleed down allowing the end user to be able to run pump gas...the end result is a car that can be used on the street, but has more performance potential at the higher non-street rpm ranges.
I would recommend a book that Hot Rod put out that combined all the articles they ever had written about cam theory, what happens if we change these variables...although written with the other brand V-8 in mind, the changes to cam characteristics are uniform for all engines, but some engines like certain things than others, so what may work for a Chevy 327 may not be 100% true for the small bore long stroke 6 cylinder.
"High Performance Camshafts" by R.M. Clarke, amazon has used copies at about $10+shipping is worth the $10.
