As you rebuild the engine and work out all the issues, be prepared to have the vehicle down for 1-2 weeks. Depending on environment and experience, job can also be accomplished in as little as a weekend.
GM 3400 SFI reference shots of a pulled engine... for reference (helped me).
This photo of intake manifold sums up the state in which the engine was. I washed it, cleaned it with a brush in hard-to-reach areas, and painted it using high-heat paints. I chose to stick to 'factory look'.
While cleaning the cylinders/block, be sure not to create scratches. Use a non-metal dish scrub and a degreaser.
*Ideally you properly relieve pressure with a special tool by connecting to a port in the fuel rail.
Upcoming lip design I'm working on will attach to factory bumper with very little work involved. Limited edition run; get in touch to reserve yours.

I never got into SUVs – they always felt too bulky, while not being overly roomy, so being a father of three, I prefer the #vankulture scene.
This is the most highly optioned minivan of its time:
Thunder was a rare package and as a result very few vehicles were produced – especially with this color combination (~10 our of 40,000), which makes this one of the most rare vans on the road today.
