Retrofit hydraulic roller lifter

Torrance1 said
Hello everyone
I have a couple of projects going on at the same time.
One is my 74 Dart Swinger, the others are a 1956 Packard and a 62 stationwagon Have any of you done a retro fit Hydraulic roller?
I'm not concerned about the cam, but the lifter dimensions and the push rod length
Did you go with the link bar or dog bone style keepers?
and of course what brand lifter did you use.
Thanks
Best

'89 -'91 318 TBI roller engines, stock lifters, stock pushrods, stock heads, stock rockers, stock 9.2:1 pistons. Can be converted to carburetor.

Find a stock roller engine and go from there. Lifter bores stand up higher on the roller engines to accommodate the roller lifters.

Edit:
The above Roller Engine has reinforced upper lifter bores that are factory cast into the engine block.
