i just ordered this cam. yay i know it is big. but i think it is going to work well on the button. so i do have another question. is a good boost and or nitrous cam a cam that has a bunch of overlap??? im still trying to figure this all out. i have been told that the more overlap the better when it comes to a good F/I cam and the less overlap the better the cam for N/A.

224-228-581-581-114+4--comp.

 

Thats similiar to the cam I am going with. Mine is a 224/224 581/581 on a 112LSA.

 

I've heard the good nitrous cams are the split ones

 

that cam is going to be a hoss man way to go but i did also hear that good nitrous cams are split ones even though not many people use them dunno why though but hurry up and get thatbeast in......

 

sounds like its going to be a nice cam for that truck

 

You have it opposite. More overlap for N/A and less overlap for a power adder. General reason (many theories, this is just one): With overlap (intake and exhaust valves open at same time), you get a scavaging effect where outgoing exhaust gasses assist in sucking in fresh air from the intake. This gets more air into the cylinder at higher rpms. That makes more top end, but also created that lope at low rpms. Under boost or nitrous, with overlap you get your intake air charge going out the the exhaust valve. With less overlap, you allow the cylinders to build up more pressure and make more power. There is more to it that this, but this is the general idea.

 

Sweet buy! Looks like us truck guys are starting to get a little more aggresive on our cam selections on everyday vehicles. I like it!

 

I'd probably gone smaller myself, and a more n-a oriented grind with a very efficient exhaust... Long tubes, dual cut-outs for the track to go along with the 150 wet. jmo

 

Another thing to consider is motor size. The "same" cam will be more agressive/radical in a smaller motor than it would be in a larger displacement motor. For example, I had a .292 Hydraulic cam in a 355" Chevrolet (Gen1 motor) that sounded really radical. That same cam in a 406 was not as radical. I think a cam that large in a 5.3 would benefit from some cylinder head work. Although that could be said for a stock motor as well, I think the RPM range for that cam would REALLY benefit from flowing more CFM. What is the advertised operating range for that cam anyway?

 

Maybe thats in the plan. I remember you having some heads on order before the tranny went. Are you back in the market? I agree that headwork would probably make quite a bit of difference with a cam that size.
