G54b blocks

[Zaque]

Is the standard 2.6 block the same as the conquest turbo 2.6 block? What are the differences?

[pennyman1]

conquest block is the same as a truck block, but has oil squirters under the pistons, and all are wide blocks as far as I know

[Zaque]

Are the internals as far as the crank and bearings and what not the same as well?

[BradMph]

a 2.6 block is a 2.6 block. Internals are same and should be the same from 1979 to 1989 in the Montero, Pickup and Starion.

Crank Part Number is 99072B
Con Rod part number is 413

Oil squirters can be machined into the block if needed

[pennyman1]

crank journals can be different sizes - 60 or 66 mm - all rods are forged. Cranks in intercooled 2.6s are nitrided for strength.

Also, the rear of the block is different for the automatics.

[pennyman1]

For the truck blocks yes, but for the conquest and 87-89 blocks, all are wide blocks

This can help verify block bellhousing, years and bolt patterns. Ignore the highlighted areas
