400+rwhp with Heads + Cam
I second the used AFR 205/210's and a a small-medium cam. I had the PRC 5.3L heads and 228r 114 LSA combo and did NOT like it. MPG was 18 at BEST and anything under 3000 felt soggy? Poor throttle response and just not enough low end tq for 6th gear cruising if a hill cam up. Keep in mind I have a 3000lb can and 4.10 rear.
The port design on the 205/210's have GREAT low end and carry up top like most 225+cc cnc'd gm casting heads.
Used 205/210's with springs ~$1600-1800
Cam $400 low to mid 220*'s on the cam.
Head bolts $50 or GM $200 of ARP reusable
Cometic .040" head gaskets $180
LS7 lifters $130 (suggest Johnson or morel if you can manage $400)
FAST 102 & 92mm TB $1200 (if you can manage)
LS3 injectors $130
1/2" injector spacer $40 (for using LS3 shorty injectors on an LS2 setup like the FAST)
EV1 to EV6 adapters $20
Trunioned rockers $150 (I have some for sale btw)
That's $4400 for the highest of everything I listed. ~$2800 for cheaper lifters and no FAST intake and TB.
That's a great setup that will net you awesome tq and probably pull 430-450rwhp.
What kind of springs to you guys suggest for this application? Single Beehive or Dual? I can't seem to find a straightforward answer. Thanks in advance!

You'll want something in the 227/229 range. AFR's like a small exh biased split. All depends on what you want out of the car. The Tick SNS tq max lvl 1 or 2 would be nice.




CAM MOTION, gentler lobes as mentioned compared to the TSP
224, much better valvetrain stability, reliability, longevity, and revability!
Something like 223*/227* 115*+3* .610"/.590" or
227*/231* for a little more top end that is the max you would
Need to 6500-7000 RPM! With great low speed Driveabilty and rip
Your head off throttle response!
3.73:1 will be perfect.
Thats the beauty of the AFR heads, small to mid size cams deliver
The best of all worlds! And decent mileage to when you are just
Cruising down the highway.

As far as cam size with a good set of heads keep the intake duration in the 226-228 range and the lsa in the 111-113 range. Keep the exhaust duration 0 up to 8* higher than the intake duration, depending on what's more important to you, power below the curve or high rpm power above the curve.
