Build problem

Post by barh »

Hello everyone, I just finished a clegg 4.6 build. the motor runs extremely hot. I have a new radiator and all parts including the head are new . no reconditioned parts. quence is at 40. this thing wants to run at 210 deg even at idle. it is a dog I am very disappointed with it so far. I have about 300 miles on it so far. does anyone have any suggestions as to what I should look for? I have double checked the thermostat even tried to run it without one. still runs hot. it is the same radiator & fan I had before the build & it ran 190. If I gas on it or turn on the air its all over. thanks

Did you check your clearances after machining?

Is it getting enough fuel and ignition timing?

Check for air in the cooling system. Again. Then do it all over again.

I'm with Russ, lead fuel and/or retarded timing will cause those issues.
You can get more power out of ANY engine!!!

x3 timing and fuel.

If it had normal power I'd say air bubbles etc, but you said it doesn't. Distributor off one tooth?

clearances were checked & I have a blueprint sheet. Motor was assembled at accupro race engines after machine work was done. I will recheck the timing but have checked twice. it does still have stock injectors could this be the problem? I wouldn't think so since it heats up at idle also. the throttle body has been bored & the only other thing was to change to a header. thanks for the reponses, Darryll

Stock injectors? There's your problem.
