Looking at mid to late 90's Chevy trucks. Does anyone know what year Chevy starting using the Vortec SEFI 454 big block.

1996 What size truck are you looking for?

i have 98 1500 with a 350 voretc. it puked tranny around 95k miles. Since then i put like 30k on the new tranny and seem sok. I know the 350 vortec had aprpblem withte intake gaskets they are WAY to thin and fail prematurely. MIne went and i had to pull the intake manifold and install new ones. I'mnot sur ei the 454 vortec had teh same problem or not.

Yep, 1996 is correct. Highly recommend that year or later.

R Addiction,
I'm looking at dually's. Kind of scared of the 6.5 diesel. Probably only use it 5000 miles or so a year anyway. It sure would be nice to go new, but I would rather dump the extra coin into the boat.

I put 100K on my 96 Chevy Dooley 454 auto. Towed more miles than empty. Never had tranny problems. C1500 had a 4L60 trans, C3500 has a 4L80, different transmission. Never had intake gasket problems either.

Almost 95000 on my 97 dually. 454 auto....knock on wood, no major problems

I hear ya on the 6.5.....What are you looking to spend?

I'd say 10 to 15,000. I'd like to find something like DanB's truck shown above. Would like to find something with 75K miles or less.

Just picked up a 97 dually with 71 k for a customer 4x4 ext cab 12.000 97 454 is a good year!
