Re: 406 efi build
I think you'd do better with 30 or 32...
Smaller injectors with higher fuel pressure, tend to do better than too-large ones with low FP.

Re: 406 efi build
Mine is a close comparison
I have a stockblock 400 with 4.125 piston and 3.75 crank and 5.565 rod.
I have the 280xfi (flat hyd version though)
9.2 compression, 1 7/8 headers, LT1 intake (miniram),
3550 lbs with me in the car, 3.75 gears, 3500 stall
12.1@111 na

Re: 406 efi build
According to this calculator
http://www.wallaceracing.com/hpcalculatorquarter.php
Your HP computed from your vehicle ET is 355.57 rear wheel HP and 395.08 flywheel HP.
Your HP computed from your vehicle MPH is 350.87 rear wheel HP and 389.86 flywheel HP.
I think I was a 1.64 60ft
Remember, hp means nothing if you don't have a proper combo (gears, stall, traction)

Re: 406 efi build
On AFR's site they have listed a 383 with that cam and the 195's at 10:1 compression ratio and performer RPM making just over 500 at the flywheel. So figure a 400 making an easy 25 horepower more. If you haven't bought the heads yet and are building a 400 pay the extra and go with the 2.08 valves or move into their 210s and get a 2.1 valve.
