Hey everyone. I'm stumped. I got decent amount of money to drop on my 350 in the 79Z with the goal of breaking 300 horses. I thought I had the right setup, but a compcams rep told me it was more like 270-280rwhp. Heres the setup I was gonna get.
Upgraded vortec heads~up to .550 lift
Eddy Performer intake(willing to go up to airgap)
Eddy AVS 650cfm carb
XE 268 compcam(recommended to me by compcam rep)
I currently have headers, true dual exhaust. Th350 tranny. 3.42 gears.
I've read every article in my "vortec searches". Learned alot over the past 2 months, but I seem to have a hole or holes in the equation. Sorry if I sound like I want you guys to do the work,thats not the case it's just that I've seriously read dozens of articles and tons of threads on all these questions and still not sure were the problem is.
Note this is still gonna be a (10-20 miles) daily driver. Don't mind sacrificing fuel mileage, but don't wanna get too crazy. Is this asking for too much? Let me have it fellas, I can handle the truth.

j/k But any advice would be appreciated. Thanks
