I was curious if the metal that makes up the mouth of the TB is thicker than the other aftermarket TBs. I cracked the mouth of my last TB and was looking for one that has a thicker mouth. From the pictures it looks like it has more metal to make up the mouth of the TB

Also, is billet aluminum stronger than cast aluminum??

 

Billet is stronger than cast anything. I have a BBK 58mm and im 100% sure that the summit piece is better than mines.

 

Thats what I originally had but I had to clamp down on the mouth with t-bolts to keep from blowing the intake elbow off I broke it and now Im shopping for something stronger

 

my buddy has the summit one
he just bolted it up and had none of the issues many complain about with the holley parts
and also for your application you might want to look into the AS&M mono blade its one of the best quality pieces out there plus flows more

 

AS&M is where i would get a Throttle body from. By far the nicest one on the market.
