Default Bbk 58 Mm

Just bought it off of Ebay. I was wondering what performance should I see from it?

Also I was at Sunshine Last Wednesday and when I pulled up to the line my temp was 212 and at the end was 180. It was running bad like hesitating and popping a little. Last week before that when it was realy cold out and my temp was like 180/190 at the line there was no trouble. Do you think it could be a coincidence, or do you think the 212 was a little warm?

Do you have a big healthy cam, ported heads, and a matched intake?

No? Then you wont notice a lick of difference.

Unless you have supporting mods like Corey mentioned you won't see a huge difference. For the 58mm tb, you will need to have the opening on the intake openened from 52mm to 58mm to match the new tb. Also you will have to cut the rubber elbow on the sides to get it to fit over the larger tb opening.

That's what he said, but he prolly went back with the stocker after he realized he paid $400 for a worthless throttle body.
