Re: Gen 5 454... what retro fit hyd roller lifters?
If you have a gen5 BB,you dont need retro rollers,just rollers.
Gen 5 blocks were from 1991 til 1995.
Gen 6 started 1996,mark 4s require retro rollerts if you want them.The last mark 4 year was 1990.
Check your casting numbers over at mortec.com
Also,I was told by a Summitracing techy that Sealed Power was the manufacturer for the GM rollers of those years.
EDIT-Just reread your post.Did you not mean to say retro?
GenVI 454,Autogear M-22W,Moser 12 w/3.42s
'67 Malibu,468 w/TH400
