1990 454ss

I have been looking for a 454ss for 5 years now I found one and it has 52,000 miles. It all ready has a cam and a intake and a carburetor and a full exhaust and it lowered 3/4. The 2 owner took the ac off of it. My plans are to put the ac back on. Install Holley sniper efi and just clean it up

Awesome truck! I've always liked them, but with 3 young boys, back in 90, I had to have more room in everything.

Building a small, high rpm engine
with the perfect bore, stroke and rod ratio is very impressive...
like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.

Cubic inches is like Indiana Jones with a cheap pistol....

Re: 1990 454ss

What an improvement under the hood. With the sniper, Chevrolet logo black valve covers, red spark plug wires, black air cleaner and headers it looks really clean. It’s in really good shape.Do you have any plans on what your going to do to the truck next. Besides the a/c. It doesn’t look like in needs any improvements.Or are you just keep everything as is and drive it
