The only thing about a large overbore is that when you do overheat, you are at more risk of permanent damage. But the overbore doesn't make the engine overheat. You can run a remote radiator. Buy why? The pump will do fine, a performance pump will do better, but your main concern is correct piping to the radiator and getting enough air through it. That's hard if you mount in what really is the wrong place. Much easier to fabricate a decent mount in the original location for a good radiator. Use a radiator that's the same core area as a full size pickup.

I agree with him, though, the .060 over bore isn't a real issue as far as a properly designed and functioning cooling system is concerned. I've built more than a few V8 small block S10's, even two with big blocks in them (that was a serious tight fit), and never had cooling issues.

My plan is to get electric pusher fans mount them to the radiator, cut some louvers in the bottom of the bed up against the cab and form some sheet metal on the sides to put all the air coming in across the radiator. The radiator is out of a 4.6 L v8 ford f150 Jamesg  Forum Newbie Posts: 15 Loc: aztec, nm Reg: 12-23-11 02-09-12 08:02 PM - Post#2188997         In response to IgnitionMan thank you i appreciate your help, seeing as how you have done a few s10 v8s ive got a few questions that you may know the answers to. im putting the v8 into a 93 s10, it originally had a 2.8 v6 with a t5 trans, im trying to figure out if its world class or not, if it is WC would that hold up to a roughly 400 hp engine or would an old 4 speed saginaw work better, also can the original s10 alternator wiring be used on a 3 wire alternator from an 83 chevy? thanks again for your help Stinky  Senior Member Posts: 959 Loc: Whitewater, CO Reg: 05-25-01 02-09-12 08:48 PM - Post#2189007         In response to Jamesg I once had a VW bus w/a Toyota 21R in it...the radiator was on the front bumper and it was not a problem getting the water to flow from the rear, to past the front of the van (the bumper was moved forward a foot). It ran at 180, even on the hottest AZ days and the fan almost never came on. I've also had two sandbuggies...one w/a Pinto motor and the other w/a Honda, transaxle, Mcpherson stuts and all. Both of em had the rad is a somewhat "odd" location (but not as much as you would have) and waterflow wasn't the problem...The Pinto didn't even have a fan, but the one w/the Honda, the fan ran almost all of the problem and it always ran hot as the radiator was at a 45 degree angle. The dif was that amount of airflow as the Honda had less pipe. BTW, all of the above, hauled butt. Tons of people move the rad to the bed. The problem they have is not waterflow, but air flow.
