I got a problem :(
I got a problem :( I put the motor in my car started it and no oil pressure unless reved up. Is there anything u can put in the oil to unclog the oil pump instead of takin off everything and cleaning the oil pump out by hand ?

You keep reving that motor and you'll be sorry.

How big of a PITA is it to replace the oil pump? 
Check for the plastic diverter cap on the back of the engine... on ordered crate engines they are usually lacking a small plastic plug in the back of the engine behind the rear main cover... you have to pull it off your old engine and put it on the new one. This diverts oil up to the oil pressure sensor... Car will have oil on the cam and crank/bearings, but never makes it to the sensor without that plug!
Well I was thinking, I hadn't driven my car in over a month and since then our yearly heatwave has rolled in (92F-94F). Last "night" I kinda tested my theory. I let the engine idle for like 20 mins and my idle psi was a little above 40psi. I then drove it around for 30 mins and the lowest it dropped was a hair below 40 (idle). I think what I really need is an oil cooler. Any recommendations?
