TB's Are they effective?
 

Hi~

just wondering if you have to port the TB elbow if you buy an after market (larger diameter) TB? I'm thinking of going with an Edelbrock TB, which is 75 mm. What sort of adapting would I have to do ion order to gain full HP potential?


Thanks:smoke:

HI!... You have to port/polish the TB ELBOW to match the larger TB or it will be useless to install. Here's a few pics of mine.

Hey Neal~

Who would be able to port/polish, I don't have the tools for that.
I was thinking about getting the Edelbrock 75mm TB, so I would have to bore out the elbow to 75 mm, right? What did your use to port/polish your stock TB?

thanks again for your help!
