Is there enough of a gain with a 6 blade over a 4 blade fan? I thought I saw on here where to get the smaller pully and spacer. I'm doing everything I can to help cool the car down before I have to pull the heads and drill in the steam vents.  Thanx

I’m in total agreement with John.  The steam holes are not for additional cooling but were provided to solve a problem with air being trapped in the block when the coolant levels got low.  I go out of my way using blocks and heads that do not have steam holes as they are inheritently stronger and less prone to cracking.

Boiling the water out?  If not then double check the gauge for reading correctly.
