I have a 92 bronco on a 78 chassis
40" tires
3:73 gears
Stock C6 Trans

Had a bone stock 460 in it

Well it came time to rebuild

So I did a stock rebuild with

429 timing set
Preformer intake

And a lunati cam it's been a couple years now but I think this is the cam or close to it

Advertised Duration (Int/Exh): 250/256
Duration @ .050 (Int/Exh): 207/213
Gross Valve Lift (Int/Exh): .503/.535
LSA/ICL: 112/108
Valve Lash (Int/Exh): Hyd/Hyd
RPM Range: idle-5000
Includes: Cam Only

I finally got it going and it's like it's not getting fuel

It's
Extremely week
Won't pull past 3k rpm on the floor
And Cuts in and out

So I borrowed a holley blue and it was better but not fixed

It's has one of the crappy 600 cfm Holley carbs (not 4150)

Do I need a carb ?

If so which one?

Thanks Micah
