Richard nailed all the major issues pertaining to 460/7.5L
On my 97 bounder built on a 96 F53 chassis, i have replaced the fuel pump, the frame mounted filter, and the ignition module which mounted under the front hatch/hood on the firewall on the driver side, i also flushed the brak system snd filled with fresh Dot 4 brake fluid ,


I can explain it to you.
But I Can Not understand it for you !

Thanks for the replies… I just went and picked it up today to take it the exhaust shop. Drove it without any issues. It does feel like there is not a lot of power but I figured that is because it is a gasser and is so big. I don’t expect it to be like a hot rod but figure it should have more power than it does. As it is, I wouldn't trust trying to drive through even the smallest of mountains! It has sat for a week since I parked it so leads me to believe the excessive exhaust back pressure is causing the lack of power and maybe something to heat up which eventually causes it to lose power. I am told braking is affected when the exhaust back pressure is excessive.

Good luck, but that 460 isn’t known for back pressure, headers will give you hp.

Check your fuel pressure, most likely cause. Ignition module is cheap and easy to replace. Likes to fail when it gets hot.

Exhaust back pressure has NOTHING to do with braking. Your brakes are hydro-boost. Meaning the power for the brakes comes from the power steering pump.
