I need to up grade to a 58mm throttle body, which one do you guys like the best? Please let me hear what you have to say.

Thanks

 

Ask 50 people and you'll get 70 different opinions. My research led me to the Arizona Speed and Marine one (AS&M). Others prefer the BBK, and others the Holley. Some hate Holley, some hate BBK. I haven't heard much bad about AS&M though.

I do like Holley's red blades.

thats the SECOND time ive fallen for your sig!!

 

Well if you are looking for a nice looking quality piece and are willing to pay the big bucks for it then the AS&M is the way to go. My second choice would be the Edelbrock/BBK unit.

 

I have had zero probs with my 52mm holley, good quality, idles fine..

though now I need a 58mm now and the AS&M is too nice not to get.. if you have the dough, that is the one.

 

another vote for AS&M

see ya
