Yup...makes buying parts for the 2500 fun. You have to ask for 1 ton parts.

The floorboards and door sills are still relatively good, so i'm probably looking at new quarter panels, doors, and a bed. I'd like to get another pickup bed but will probably go for a steel flatbed if its cheaper.

Sorry guys....its just not worth the green paint.

I would assume it to be 4 bolt... most of this era were automatically the sought after 4 bolts.

What'* special about the 4-bolt?

This is all www.wikipedia.com has to say:

Quote:
400
A 400 in³ small-block was introduced in 1970 and produced for 10 years. It had a 4.125 inch bore and a 3.75 inch stroke. Initial output was 240 hp. While popular with circle-track racers, the engine was prone to cooling troubles if cylinder heads from other blocks were fitted without proper modifications. The 400 produced a lot of torque at low RPMs compared to the other displacements and was used primarily in pickup trucks and the large B-cars (Caprice/Impala) but also found use in Vans which could not take a big-block motor. The 400 was eventually discontinued due to its inability to meet EPA emission regulations in place in the early 1980'*.

The 400 was unique compared to all other displacements for 3 reasons:

Due to the siamesing of the cylinder bores in the casting - there was no space between adjacent cylinder liners - this block was rather rigid and not prone to the cylinder bore flexing of the other displacements.
This block used a much larger 2.65 inch main bearing assuring that crankshafts from all other blocks would not fit without special oversize bearings.
This is the only small-block that used a 5.56 inch long connecting rod compared to the 5.7 inch connecting rod in all other displacements.
While Chevrolet never produced a factory performance version of the 400, it is highly sought out among racers who participate in the very popular 406 racing class - so named for the displacement created by a minor overbore. Destroking a 400 block with a 350 crankshaft creates a 377, a popular combination for dirt track racers. 400 blocks are nearly impossible to find as salvage today and as such the racing market is fed by 3rd party manufacturers who offer improved versions of the block.

IIRC

4 bolt means that the crankshaft bearings were held in by 4 bolts instead of the typical 2. This added support keeps the crank from walking and takes tons more abuse than typicaly 2 bolt main bearing caps.

Bingo. However, a 4 bolt main is an overkill for everyday use. Unless it'* your race car or modified very heavily, a 2 bolt main is VERY feasible.

Abuse or serious pulling power is the key to the desire for a 4 bolt.
