Default Throttle body question

If I where to go le2 package with a 383 short block setup would a 52 mm throttle body be decent for daily drive or could i streach it too 58 mm

also would it be better for me to go holly throttle body orr can i settle for a BBK would love to know what people feel about both. . .

I would go 58...52 is more for a stock cubed motor with bolt ons. A ported stocker would work and cost less.

Go with a 58mm. It made a huge difference in drivability when I replaced the stocker with a 58 on an LE equipped motor. All the TB does is let air into the engine. It doesn't work like a carb.
