That depends a lot on how often you may repeat each digit, and what operations are allowed. If you just want to write a four-digit number, using each digit once, start by writing the largest digit on the left, then continue with the second-largest, etc.
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.
The biggest 4 digit number that can be made from using the digits of 850236, using a digit at most once, is 8653.
The idea is to start from the left, and use the smallest digit possible in each case. For instance, the smallest option for the first digit is 2, the smallest option for the second digit is 0, etc.

No it does not. Chevy did not start using a roller cam until late 1995.
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.
If you only use each digit once the number is 6 (it is a simple permutation and 3!=6). If you can repeat the digits there are 9 possible 3-digit numbers that start with 6, 9 that start with 7, and 9 that start with 8, giving you 27 possibilities.
The biggest 4 digit number that can be made from using the digits of 850236, using a digit at most once, is 8653.

the answer is = first 2-digit number by using 48= 28,82 and in 3 digit is=282,228,822,822
There are 27 of them.
