Which one would you recommend or not recommend? 94 Z28 auto with cam and bolt ons.

 

I would save your money. They are worth a negligible amount of HP with your mods - not worth the price tag IMO.

 

I am doing it because it has to be done. Any suggestions will be appreciated. Thanks.

 

Interesting. Why does it HAVE to be done?

I offered you a suggestion so hopefully it's appreciated.

 

I am running a 700r4 in my car and I need a TB that has the throttle valve bracket on it. The stock TB doesn't have it, but from what I have read all of the 52mm do. The guy who originally put the 700r4 in my car fabricated a bracket on my 48mm TB and I don't think its exactly where it needs to be because I keep burning up transmissions/clutches. I do appreciate your insight. I don't understand why the 52mm TB range from 200-360 in price. I am assuming it is because of brand. BTW....great 60ft and 1/4 mile times on your car.

 

The $200 ones are probably cheap Chinese ripoffs.

The stock throttle body from a 93 has the TV cable connection, since they used the 4L60 = 700R4.

 

I have a new in box BBK 1540 52 mm for 92-93 auto with bracket. A bargain @ $ 280.00 shipped.
