L67 with ls7 lifters

[Benjamin Whiley]

Hey fellas I know this has probably been said somewhere but I don’t have time to research XD. I’m in the middle of doing a gasket kit on a l67 from a vs Calais and was wondering what extra things I have to do if I was to change to the ls7 lifters instead of just new stock ones back in. Thanks in advance boys and keep up the good work everyone

Just check the pre-load, you might need different length push rods to get it right.

Yeah sweet as thanks bro, also you wouldn’t know what ratio diff is in it would you by any chance?

VS should be 3.08 ratio BW75/78. You'd need to look under the car to see if IRS or live axle and again you'd need to test the diff to see if open or LSD.
