Engle Roller Lifters

Hi
I was wondering what the difference between small block and big block Engle roller lifters would be?
I have a set of small block lifters and was wondering if they could be used in a big block . Tie bars ? Anybody...................

the center to center may be differant.... stock RB stuff is 1.8" center to center

Are your tybars captured or removeable and changeable? If changeable try them in your block and see if the ones(tybars) on there will work or not. Both motors use the same diameter roller lifters, if there captured, not changeable, call Engle562-232-7079 and ask them

I've used BB lifters in a SB and if I recall the
spread is very close but the shape of the bar is way
different to clear... I ones I used I cut the rivets
loose and changed the tie bar then welded the rivets
back on

Thanks all . I don`t currently have a BB to check m just wondering.
