My freinds race car has been runnig hot and here is what I have found. what do yall think? 355 just built runs ok then about 6 laps in 220 and climbing. New alamanum radiator, race fan, shroud, hole in nose peice is completely cut out. I have notice the heads are camel hump 422 and he had ac 43ts plugs in it. Can this cause it. Also pullies are 1 to 1 but water dont seem to be moving alot in radiator. Tried several water pumps, same deal. Checked head gaskets and there good reassable and same deal. I hear that that is the wrong plugs for the heads. IS this true? Also the fan was to far in the shroud so I am moving it out some as well. Just looking for opinions.

The air exits the fan at an angle,if it's inside the fan it slows the air,i have a shroud like that and switching to a good shroud made a huge diff.Also use the stock air dam under the rad,this helps also.

Oh well ran 35 lap feature never got over 210 and it went boom at the checked flag finished 6th. Pulled heads and number 7 piston expolded and x rod twisted. Number 3 piston busted. Salvaged the heads luckly? What caused it I dont know. but the oil pressure was about 45 running and thats a little low. Blow by was also terrible before the boom it was pouring out breather on valve cover

Were they stock cast type pistons? Depending on the piston, it could have just pulled them apart. Too much timing, low grade fuel could have done it too.

When you run a motor hot for a while they loose ring tension,at least that is my experience,that was probably your blowby.
