There is no way you going to make over 400rwhp. I called you out on my first post. There is something up with your setup. That 420/430 is a pipe dream.
Also why do you keep calling the xe 224/230 a baby cam?

Its not that small, and when you look at the lift numbers its decent sized. As for your heads, no one other than someone who does porting for a living would get the flows you did. Especailly on the exhaust.

When you come on here saying all this wacky stuff people are going to call you out. Mainly because many have already been down the road you are and there not buying what your sellin.

those numbers are realllly low...you must be running an auto with a large stall/rearend, or at high altitude? as long as it runs good though thats all that matters

I dunno the DA in Jefferson... but I'd say that it has to do with where you are and your components. Dre is onto something. HP numbers are great... it's the ET and MPH I care about.

Where are the first 3763 rpm's?
i also don't see 360 hp and 402.6 ft.lb of torque that you wrote in your first post (i see 357 and 397???)...
Anyhow if that is all you seriously have done those are some GOOD numbers...
good for you!
let us know what happens when you get injectors and a tune...

well the 360.1 & 402.6 is with WCF and yes that is all i have done to the car neverming the exhaust leaks, but needing bigger injectors and being ( untuned) is what is awsome to me there are guys with LE2 setups not doing what i am and im untuned. and yes hp may be low compared to the le2 right now but it will be way higher once i get injectors so i can rev to 6500 that 1400 rpm to make HP.

But I'm not saying I believe all this just yet!

im amazed at how many people think only lloyd and AI can get good numbers out of heads.

Theres two local shops to me that can get 280ish on the intake out of stock heads....one does hand porting, the other does CNC
