Re: Adding telltale to ’72 V4

"V-4 blocks
The V-4 configuration presents some interesting issues for locating the indicator outlet. Typically the V-4s run hot on the starboard side. That’s because of a tendency to develop air pockets high up on cylinder #1. By adding the indicator outlet to the top of the water jacket above cylinder #1 you provide an opportunity to "burp" any air out of the system and fix this issue. On many of the ’73-’77 V-4 blocks there’s a cast-in round boss just perfect for locating the indicator outlet. If you don’t happen to have that boss, you can go in through the top, just behind the coil brackets also."
