what year 302 is it? what heads are you using? i ran a 750 dp on my built 440 and it was just about perfect for it. like everyone else said that carb is overkill. might actually be robbing some horses seems like a 600 or so carb may be better suited and with different jetting allow for room to grow with more engine upgrades. the disc brakes probably added an extra 40 hp haha sorry i had to say it.

I'll bet he's got a high performance double roller timing chain also.
