i'm building a budget 355 to take the place of my now blown up 305tpi and i'm putting the hsr on the 355 and i'm looking for a throttle body. i like the price of the summit throttle body and i'm thinking how much could a company really screw up something like a throttle body? have any of you used something like a summit throttle body? and have any of you heard any bad news about the summit throttle body? and when buying a throttle body for the hsr i buy a lt1 throttle body not a tpi throttle body right?

 

Anyone have an answer to this i would like to know too.

 

unless you are running around 300 hp to wheels.....dont worry ab the throttle body size......waste of money....if you are i am running bk 52mm throttle body with 385 and no problems you buy a tpi throttle body....the lt1 intake and hsr intake are different....they look similar but run tpi intake TB
