Valve cover clearance
Thanks Rusty.
I did the original "How To" on bigblockdart.com back on January 3,2007.... It has since that time had 65,000 views....
I have just recently revisited the heaterbox mod and now have it with no motor to the outside of the box at all.. The motor is completely contained inside the heater box.
If I ever get caught up, I intend to post an updated on how to do that.
