ok I have comp lifters vertical bars. all for the .900 setup. I guess It will just be a matter of checking clearance. I suppose I could just build a 421-427 and not nave the issue. I wonder how much e.t. I would loose with a few less cubes?
Probably about a tenth depending on the combo, but it will save a bunch of grinding since you have a .900 base cam. Still need to check clearances everywhere.
