Hello,

Here we go,

I have installed a 454 in my truck but the owner who had it before me replaced the stock 350 w/ a 454, so thinking that it was the stock motor that came with the truck I replaced the old 454 with a 454 punched to 468. I think its bored .30 over!

But since I have put the new motor in I have been having temp problems, I have replaced the water pump and I have upgraded my rad to a four core rad. I have checked for leaks and have not found any, and my coolant level does not drop! What have I done wrong, also I have replaced the temp sending unit and the gauge with an auto meter gauge!

I have asked around and no one seems to have an answer, but I was reading and somone said that if your head gaskets are blocking a coolant hole in your head your motor will over heat! I could have swore I did everything right, but I am a rookie and we do make mistakes right?

The thing is my motor cools down @ when I am on the highway or on a long stretch of road with no syopping and starting, and it does not overheat when I am hauling my camper and bike trailer when I go camping. The temp gauge hovers right around the red section when it gets to its warmest point, but it has not yet boiled over!

i have no idea what is wrong can you help?

My other question is I would really like to get a cam and some headers for my truck, first I have no idea what kind of cam I want and have no idea who to get it from? And I also want to put headers on my truck, to try and pull fuel economy out of the 468. Does anyone have any idea who I should go too? My truck is 1980 k10 with a big block, does anyone run this type of set up?

Thanks in advance,
MattyJ
