I bought a set of billet rails set up for a LS2. The problem is I have a LS1

I need the adapter blocks and cant seem to locate a set. What makes matters more tricky is there is no name on the rails and I cant ID them to contact the company

Ive found several companies selling LS1 to LS2 conversion kits with the injector spacers and rail mount offset adapters, but none selling replacement blocks

There are some to fit LS1 on LS2 but not the other way around. You need LS1 specific rails.

Thanks for the info

I made a set of hold downs, it wasnt too difficult

Next question, do LS2 injectors use a different OD upper O-ring? The LS1 injectors slid into the holes rather easily compared to the stock rail and leaked when I primed the fuel system. I can take some caliper measures of the holes if it'd help

The upper O-ring is the same either LS1 or 2 should be the exact same hole.

Awesome, time for some new O-rings

They should both be 14mm o rings
