Is TB to Plenum the same on LB9 and LT1
I am looking at getting a superfueler from someone with a LT1 w/ 52 mm TB. I want to use it on my 1991 LB9. Is the TB attachment to the plenum the same for these 2 engines?

I believe it is. Checked TPIS and they sell a TB for 1992 to 1996 F-body. My 1991 is the same as a 1992 TA.

Thanks.
