Yes, it can only if you run more than the heads can handle. With the proper amount of boost she will purr like a kitten.
depending on how much it overheats.... you can blow a head gasket...warp your heads ... crack your radiator..
5.3 cylinder heads bone stock with180,000 miles flowed maximum of 288 cfm at .700
Yes. You will lose about 30 pounds switching to aluminum, and not have to reduce your compression quite as much. They will handle boost with out any problems.
Chances are that if you overload the charge in a revolver style black powder pistol, you can blow up the cylinder or blow the barrel off the end of the gun.
If the heads, cam, crank, and block is good then you are looking at about 1500 professional and 700 do it yourself
No. 305's have small valves due to the 305's small bore. Large valve heads can't be used on the 305 because the valves will hit the cylinder block. 350 heads breathe MUCH better than 305 heads. Stick with the 350 heads.
No, but if the valve is intended to blow at high pressure and you have it connected to the negative pressure of a NA engine intake so it will never open. You could use a brass plug instead as this is much cheaper and will provide the same functionality. With out a turbo making boost, there is nothing to "blow off"
The 5.4 L with the 3 valve cylinder heads has 300 horse power
I believe that is 300 horsepower for the 5.4 L with 3 valve per cylinder heads
If it has a 5.3 engine, first have the cylinder heads pressure tested. Heads with a casting # of 706 like to crack in the number 1 head bolt hole. If this happens, replace head.
I believe that is 300 horsepower in the 2004 Ford F-150 , for the 5.4 L - 3V - engine ( 3 Valve per cylinder heads )
There is no low boost light in a gtp. There is a boost meter. indicating how much boost you are pushing.
