Yes, thats what my impression was. How ever I want to go larger, I have driven big cam cars, and I know some people who have stock bottom end 97-99 LS1 who drive the ***** off them with decent sized cams up at 6000-6800. Can you give one reason why a LS1 wouldnt perform well with a 235/242 .621"/.592" 111+3 cam. I have read the drivability is good for how big the cam is. Or the SNS stage 2 cam. As far as I know both cams make good power under the curve.

 

the lope is mostly overlap. you can have that with a 224r on a 112lsa. the lobe separation angle is a lot of what you hear

not sure why you keep selecting cams that are not matched to what you have.

just to clarify the above comment about cams not affecting your bottom end....they don't, not at all, but, you do want to select a cam for the rpm range your bottom end is capable of operating in

 

yes

it won't live long and you would want more head flow to take advantage of those numbers. sometimes people get lucky and get a year out of a combo like that, occasionally even more but going far above the factory redline is never good for longevity. if you're only going to 6000-6200 you're losing cylinder pressure on the lower end vs a smaller cam. i've blown up...let's see...13 engines in my life. over revving is probably tied for danger with too much boost for a given octane.

i'm suggesting how you can make a reliable combo that's quick and snappy

again, you also need to look at the other areas of the car that need to be improved for this power as well. stuff starts adding up

the 228R is a popular drop in for the c5 z06 and often ported heads. very good match with long headers and a good air filter system. usually shifted at 6500-6600

if you can afford to buy the needed parts to optimize for a larger cam and want that, by all means, go for it. but, you need better heads and that bottom end becomes a real liability. a good oil pump is also a wise investment

 

Well this was my plan, with LS6 Intake manifold and 799 (same casting 243's I believe) and get them ported, and a LS7 clutch kit

I REALLY APPREIACTE all the advice I know I keeo going back and forth and you all know your stuff I hope I didnt offend/hurt feelings for trying to pick a different cam. Racebum...lol clearly you learned the way...is the 228R the biggest you would go? is there any cam safe with more overlap?

please correct me if I am wrong but your saying I can go any cam but the ones that are big that I want...dont have the compression they need so it wont make the ideal power. And the way most engines let go is the spinning them to high to make the power, in which its lacking the compression its would need.

 

I love my 228R, it is freaking fanstatic.

 

HOONIGAN, you've been given good advice and I'd follow it. Many good components available but it's matching them up that counts the most. When building a motor you start with the best set of heads you can afford, build a bottom end, select a cam then add FAST intake and LT headers.....not exactly that simple but in that order.....

 

Do you drive around between 6000 and 7000 rpm? If so, go for it. If you use the entire band like a street car, you want something that hits low, or mid-range. 235/242 sounds like a square port head cam first off, and is way to big. It will sound awesome and be dead until 3600 rpm. The biggest I'd go on a 346 is a 230/230ish cam.

 

same

and that's with good heads and a bottom end that will stay alive at the 6500-6600 you shift at with said cam.

a 230/230 or the common 228r work wonderful on z06s with ported heads

 

230/232 .614/.595 11lsa?

 

Futral F-14? 232/234 .598/.598 112LSA

Read up saying its nice strong cam, everyone who had it liked it.

F-13? 230"/232" .595"/.585" 112LSA
