looking for the TB gasket the one that gows between the throttle body and the radix inlet do anyone know if this is a stock GM part.

 

Yes Stock GM part....I will post the part number later. I have it someplace

 

Brian,

What gasket did you use behind the 90 mm Corvetter tb that I'm about to install?

Thanks, Jim

 

there is a groove machined in for the LS2 TB gasket.

 

GM part# 12570168 for the TB gasket you need.

 

thanks

 

I bought some gasket material from the local parts store and cut out my own using the TB as a template. Looks like its going to work fine.

 

After time, those gaskets would get stuck to the flange and the back of the TB. After the first two, I got tired of that. On the last one, I very lightly smeared the gasket with anti-seize. I've been able to reuse it several times and it doesn't stick anymore.

 

Thanks Richard. I wondered if gasket material was still available. We used it a lot back in the 50's/60's. You remind me of the guys I knew back then... when performance parts were few and far between and we had to fabricate most everything... including gaskets.

 

i just got the TB Gasket its for the 8.1 so now im thinking how much bigger is the 8.1 TB

has anyone put the 8.1 TB onthe 6.0 looks like its a direct bolt on swap
