my cam woud give you alot with a stick

its in the classifieds

244/248 612/615 112+2 its brand new

 

Good God Man!!! thats a huge cam for a little 364 isnt it,oh yeah its my daily driver. Seriuosly isnt that too big for my setup?

 

Not if you idle it up to 1000-1200rpm. The biggest issue with me having a manual trans and a daily driver is the idle being too choppy and being jerky with a sensitive throttle when idling around in parking lots etc. I personally wouldn't go with anything larger than the 230 @.050 range in duration and nothing less than a 112 LSA. The tighter the LSA the more choppy the idle and more difficult to tune. A tight LSA will produce more peak power but in a tighter band. The wider the LSA the more broad the power band, smoother idle, yet peak hp is moved higher in the power band (but not anything i've ever really noticed.) FI engines typically run a 112-116 LSA for smoother idle and drivability.

 

no its not, they run cams almost identical to those in stock LS1s. called Trex's for a 6.0 its not much actually and will be a beat with a 6speed and 456 gears. plan to shift around 7k with it and will be a beast

 

I disagree with this its the overlap that causes drivability not the angles.
For example a 220/224 on 111/109 has 0 overlap at .050 where as the same cam with 228/230 will have 7 overlap.
The smaller duration and lower lsa allow for alot greater efficency and shutting the IVC earlier= more tq.
Yes the wider lsa will tend to flatten the curve but it wont net better ET's in fact it will be worse because the upper rpm power is sacrificed alot to flatten the curve and the tighter angle makes better tq lower which is a good match for drivability on the street you can have drivability and good times with less duration and low lsa/icl

Pro stock cars run lsa's over 118 and have alot of overlap, its all about the ve's

 

I agree about the lobe centerlines and overlap. I was just keeping it simple.

Manual trans vehicles typically do better on the street with a wide LSA because they need a more broad torque curve, and especially a 4500lb + truck. A manual can't take advantage of a 3000 stall that has a tight LSA and doesn't need to make power but within a 3000 rpm band. I have very little experience with cams in automatics (helping friends mostly) but I have built and run several manual cars and trucks for the street and strip over the past 15 years and thought I might have something to add to this thread.

This is why I usually never look at cam threads because everyone always has a different way of looking at things and thinks they are right. But in most cases both or all people are right, just from a different perspective. I will stay in my corner from now on.

 

everyone always has a different way of looking at things

That's a good thing. Helps us learn from others.

 

Great info guys, but I'm a little cam ignorant, mid 230,s with .600 lift on 112 lsa this sound about right??

 

Lunati 224 / 224 563 / 563 lsa 114

their is one in the sale section.
should make that 6.0 pull hard.

 

I agree but it is just always a debate and everyone thinks they are right and guess what? They usually are. The only problem is most think the ones they are discussing it with are wrong. It just turns into a chest pounding of who can throw out another big word or scenario to describe their extensive cam knowledge to out-do another. I have just gotten tired of the drama side of it. That is one reason why we need THIS, to allow people to make their own decisions rather than listen to a bunch of educated/unedcated opinions.

1969x11- sorry for whoring up your thread but I would find something from one of our vendors that has the power band you are looking for. Maybe give a few of them a call and see what they think and compare your notes from there. I would say that most cam companies will stray on the conservative side for my tastes but maybe not yours. I'm sure you will be happy with your own decision in the long run.
