If you are trying to find out what timing chain cover you have in your small block ford this may help

Its a bathtub...no its tight jacket

We did not invent it.  We cannot explain it better that they did so here it is.

A cross section image of a water pump with the components called out.

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!

I haven't installed My new 1681C/I yet , it's certainly a burly unit But You Guys are amazing, Ordering from the website couldn't have been easier and that's the quickest processing/shipping turn around time ever. Thanks

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.

Of course consult your manual but here are common torque settings for bolts used in water pump installations
