Looking at putting a 302 stroked to 347 in my 84 stang.
Uses: Strip and Street. Mostly Strip. Looking at around 400-450 HP

Powertrain:
Heads: AFR 205 or AFR 225?
Intake: Edelbrock Performer Air-Gap
Cam: Lunati Hydro Roller Cam - 55118
Carb : Quick Fuel 850 cfm QFT-Q-850-AN
Rotating Assembly: Scat SCA-1-45310BE
Ignition : MSD 6AL-2 Box, MSD Magnetic Dizzy

Drivetrain:
Torque ConvertorHUP-51-30
Transmission: Built AOD with full manual valve body and trans brake.
Rear end: 8.8 inch. dunno what locker or gear ratio.

My questions are
1. What gear ratio and locker should I use?
2. Would you change anything in this set up?
3. How much HP/TQ would you estimate it at?\
4. Which AFR heads?

 

your set up looks good, I have a similar set up, 190 trickfflow heads, holly 750, I put down 415 rwhp 440 tq at 5200rpm, I would think you might make a bit more steam with your bigger heads..................... gears? I woud say 410's for max but 373's for riding the tourque curve. Ford racing locker has worked well for me under big abuse. good luck with your build

 

Thanks for your response. Still contemplating whether to do the 205 or the 255 cc heads. I'm kinda leaning toward the 205 for low end torque.

As for the gears I was looking at some 3.90 or 3.89s
