hay i have a fast ? will it hurt a motor id you start off with a 58 mm tb ?? its a lt1 intake i know the 48mm is good till 400-450hp but what if im going over that but not right way???

No it will not hurt but it may not be worth dropping your cash on that now. You will more than likely have to mod your tps sensor so you can adjust it to the correct voltage.

There has been a rumor going around since these cars were new that if you change the TB you'll lose low end torque, but I've never seen anything to support this theory so, if you want, have at it, but I would save your money towards something that would actually help performance. JMO

Also to get the full potential of a 58mm, your intake will need to be ported

With an auto trans car, you need to reprogram the trans pressure tables for it.
At a given TPS%, you'll have more airflow and more torque into the trans.

I'd save the money on the tb and put it towards a rear end. No such thing as a "beefy ten bolt". Some make it farther than others but they will all break. Try posting in the SBC section, probably more info there.
