Nice things people say

Sometimes people say nice things, sometimes they say nothing, sometimes they say crazy things. We collect them.

Called with a question and whomever answered knew exactly what I was asking (direction of the impeller/user error) and explained to me how the water pump worked for my old CJ. Got it installed and it works great! Thanks!

I'm running a FlowKooler 351c high flow water pump since last year. Of course I have no overheating or any issues since the quality is superb. But I'm about to overhaul my pulleys. Should I use the same diameter stock size water pump pulley or get a high flow one?
Since I'll replace all of my pulleys not only because of the water pump I want the best pairing I can get. Otherwise I'd leave it alone if I wouldn't replace all of them.

Thank you and have a great day!
Robert

The thermostat...it deserves a new name.

This was borrowed form a corvette forum in response to a question about lowering the engine temperature by lower the thermostat temperature. I love its simplicity.

Heater Hose line for the 302 and 351C

We had an call for help on routing heater hose lines for a 351C and scrounged up an image for the 302 and 351C. Hoping this connects the dots for the next poor soul staring at his block in wonderment.
