high bleed lifter or anti pump up lifter

[dmstang]

Hi, I'm looking into ways to restore vacuum during low rpm. Does anyone make high bleed lifter or instructions how to modify a regular hydraulic lifter into a high bleed lifter? This is for Ford 2.3

Also where can I get anti pump up lifter for Ford 2.3, I tried looking up the internet but couldn't find them.

Thanks.

i don't know how well a bleed off type lash adjuster would work for you. i have ran big E vacuum cams(2264.5 and it pulled the vacuum it claimed) in the past and they were ok. they have centerlines of 125-126 degrees and would pull well over 7000rpm. with the proper set of the geometry and lash a hyd cam can run to 8000 rpm. weather you need to run that high depends on a number of things.
