No adviser to speak of, I built the dumb thing in the first place, but I don't have any notes on what my clearance was with the current cam.

I don't want to disable the car for multiple weeks during the summer, just looking for a rough estimate to pick a cam in a safe range. If it ends up not being compatible with my current retainers and guides, fine, I'll have some machine work done then.

Looking to do the swap over a weekend's time if possible. Not enough space to leave the car all blown apart.
