I think when I rebuild my 67 400 with a manual trans I am going to go with a Mondello or Engle 22-25 with the 108 LSA. What else do I need in the valve train dept to make this functional?

I'd use an adjustable valvetrain no matter what.
And that cam will work but the higher duration Mondello/Engle stuff has tendency to be a bit noisy, like sewing machine.
You now have a modern piston available for that engine too.

How much are the slugs and do you have any part numbers on the valve trains components?

Introductory offer for the pistons is $645.00 shipped. That's pistons, pins, clips AND rings. They're is a post on here with pics.
Use the Comp adjustable pieces, 4843, 4542, I believe and the roller tip rockers. Try not order the whole kit as they normally come with the wrong pushrods.

Wrong length pushrods? Do I want the oil restricted pushrods that Mondello and others offer?

cutlassefi

I use a restricted .120 Wall 5/16” pushrod in virtually all my builds, never an issue. I offer them as well.
