it's an anomaly if it only happened once. You're saying a bolton ls3 has run almost 118mph but that in itself is an anomaly as well since the average Bolton ls3 cami is running 112.5mph. When trying to calculate what a car should run, it's not smart to try to get the very best anomaly run and try to improve on that. It's not very realistic to do so. That's like everybody with a stock automatic mustang 5.0 expecting to trap 115mph plus because it has already been done.Also the average cam only ls3 cami is doing a lil over 117mph fyi

This what I've been trying to say all along!

Whats a cami

[KMSRS2SS]

Mike, I'm cammed and I think we have pretty much the same setup otherwise. Before you make any decisions on the cam we need to get together and compare. I didn't do the heads, and i'm not sure I will, I will most likely have Vector install a maggie in the spring.

I saw a camaro owner on this very site refer to the camaro as a cami and thought it was a lil funny so that's what I call the camaro now!

I think the difference in flow numbers between ported stock ls3 heads Vs. Unported make it somewhat of a tough sell when you consider the other labor that would be involved. When it's all said and done it looks like a mountain of money for the gains

Agreed. I also saw somewhere somebody said go with the fast intake...in my research there is not much gains over that and a ported stock intake if any.

5.0.
Depending on how much you work your Camaro. If you don't do much your gonna lose.

but if you factor in milling and running a thinner head gasket and bumping up the ls3's weaksauce of a compression ratio, it starts to justify itself.....

yes the FAST intakes are a grip of $$$$ for the performance difference you get in return.

sure, a thinner gasket would DEFINATELY be worth doing. Not sure how much milling heads cost but that should be cost effective as well. If you have the heads off might as well do as much as you can to em. But overall, it still ends up being an expensive mod but from my experience a bump in compression seems to help more on the lower rpms when you you have a large duration cam that will kill a lot of cylinder pressure (dynamic compression). But increasing compression just for power isnt worth THAT much, going from 10:1 to 11:1 should only increase HP about 2.5%....going from 11:1 to 12:1 only increases 2.1%

your answer sounds absolute.youre a little TOO sure of it. While i think the 5.0 SHOULD win, only a small amount of variables are needed to tip the scales in this comparison so any answer would really be anyones guess.

getting heads milled can be done at any joe shmo machien shop and costs <$100 (usually somewhere around 50-60). If you are getting your heads ported, usually the person/company porting it will do it for free with the port job.

The rule of thumb I have always been told is that for every point in compression you go up, that is worth 4% in torque. and you can go up damn near a solid point, as the stock ls3 has a 10.5 c/r. So you are looking at 20+hp in just milling alone.... let alone port work and blah blha blhablahblahblahblbhalbhalbhablhalbhalbhablhablhba insert ricer internet racer math here balhblahblbhalbhalbhalbhalhbl

edit: please dont mention dynamic compression ratio again..... lol. I maybe bored at work but if you start bringing that up, I'm going to be running numbers through calculators for at least 4 hours...... lol

I know what you mean obviously.

But their is not a lot of figures to work with. It is too early to just call it an anomaly.
Thats what I am saying.

do you always have a bad attitude?
