I was wondering the diffrence between LT1 and L98 throttle bodys, as per how they bolt up. By seeing the two compared in pics, they look pretty much the same. Are the bolt patterns the same? I am asking because I'm looking on ebay for a Holley T.B. for my HSR, and was wondering the diff. between how they bolt up. There seems to be an abundunt amount of LT1 T.B. on ther so my wheels started turning......... anyway if someone could satisfy my misquided thoughts.

 

The LT1 will bolt up, but the TPS and linkage are different, requiring mods to work properly.
