An HEI from the factory but can run most any aftermarket and depending on where you are sourcing may or may not even be included.

Theoretically, yes.
Orange.
All V8 engines have the same firing order. 1,3,5,7 is the left bank, 2,4,6,8 is the right bank and the distributor rotates clockwise. 1,8,4,3,6,5,7,2
6, to 8 degrees advanced, or BTDC., will work best.
The distributor cap order for a Chevy 283 varies depending on the year of the motor. A 1975 to 1991 has the number one cylinder at the top just to the left of center. The 1967 to 1974 distributor has the number one cylinder at the top just to the right of center. The firing order is 1, 8, 4, 3, 6, 5, 7, 2.
the heads should fit as long as your not trying to put them on a big block
The make and model would help because Ford, Chevy and Mopar made small blocks.
One Block Away - 1975 was released on: USA: September 1975 (limited)
8 Degrees BTDC. / Before top dead center. Be sure to unhook the vaccum advance on the distributor when setting the timing.
1975-76
