Hey guys almost done with my swap will post pics soon I have a question tho wich cam lify would be better for the lt1 I need a lil help with deciding wich one would be better please help also help with the valve train with one would work better and something else which harness would be the.best to use cause I.been looking aorund and some people say about the caprice cop car.cause of.the ignition switch.but idk....

 

if you aren't looking for super serious power, do the lt4 hotcam kit.

 

thats the thing id gonna be turbo with fully built heads and the lifts on the cam wich one would be good

 

That's where you need to specify what the applications were. A turbo cam is gonna be different from on specifically for all motor. I don't know which specific cam is good to go with for turboing. In theory you don't want a super high lift with a turbo and not as much overlap either. The reason for the lower lift is that high lift takes more to work, and the turbo is forcing the air in any ways. for the lesser overlap is because you don't want the charge to blow straight out to the exhaust. Do you already have the heads? These 2 places are highly recommended by alot of people on this forum and also on LS1 tech. They do ported stock castingsand get very good numbers. some one can point you into the right direction

I plan on getting a set from Advanced Inductions in the future. They get the more consistant numbers because they use a CNC machine for the port job

 

I wana keep the stock heads and get them ported

 

depends on how much money you want to spend. To make power you'll have to spend. I don't know if you have a good porting guy near you, but these guys get the numbers. At a bare minumum have them design a cam for you.

 

All I trust him to do is the heads lol, the thing is how much lift would be perfect for a car most problaly daily driven, and at the same time put down good numbers

 

I mainly deal with N/A setups, so I don't know what would be the ideal numbers you're looking for. I don't want to throw out a number that sounds right in my head, and mess up your engine or make it under perform. I'm directing you to some one who makes it their business to know the right number. If anything some where about .450" lift and and LSA of 114ish with 1:1.5 rockers. call one of the places tomorrow, and tell me what they say is the best grind. I'm kind of interested to see if my numbers in my head are pretty close to what would be ideal for a mild turbo cam.

 

Ill let u know tomoroe I have a good place in mind is GM express they should know

 

What you need is a company that isn't a garage with limited resources for R & D.That said you could call the tech line for Comp Cams and make use of their Cam Quest program on line.Tell them what you want and they will tell you what you need.If it is a flat tappet cam here is a article that might help you with a outline.

I found the cam brand new with lift of 576/571

 

that is a serious lift. what ratio rockers, what's the overlap and duration, who made it, is it billet, how much boost are you planning, what's your compression, is it solid or hydrolic lifters? How much power are you looking for? and is it going to be driven on the street at all, or is it strictly for the track? These are varialbles that need to be addressed before choosing a cam

That is bigger than the cam that I put into my LT1. But the one a I chose is for all motor, still street driven, but ready for the track.

 

Is gonna be for both track n street block is gonna get bored out to a 383 forged pistons, fully built heads, lifters springs and the rest is still bein decided, the.engine is basically gonna be a.daily driven track ready car, car is.gonna get tuned by GM express racing, boost not decided on that yet either is most likely gonna be wats safe for the engine and give me good hp and tq, and those I want it to be a.surprise for myself lol

 

so what are the rest of the specs on the cam?

I understand just building it to see what it puts out. you just don't want to put something in that will take the fun out of driving it on the street. Then you won't be happy til you take it apart again to replace the cam.

 

Lift 576/571
Duration .050 230/236

 

here are the specs of the cam

 

have you decided on the pistons yet? make sure they are forged, and you want to be lower than 10:1 compression. Did you get a hold of GM express at all? Did they give any insight as to what whould be some ideal parts?

 

Yeah n the pistons are gonna.be forged

 

sounds like forged crank and h-beam rods too. sounds like you're going radical. when it comes time to pick the turbo, i won't be able to help with picking one out.

 

Hell yeah bro better to go all out and I havent decided on.the turbo.yet
