Yes.
The aftermarket ones uses the inline bolts.
Some blocks only have the inline starter bolt patern,you can drill for the other pattern in your block if needed.
I just bought a lightweight starter & can use a 153 or 168 tooth flexplate.
Low torque bolt pattern are inline,the Higher torque starters have the diangle bolt pattern.
Low torque startes are shorter than the high torque starters.
(Factory type)
There are high torque & low torque starters (being stock type)
If you buy an aftermarket light weight starter,they usually will work on both flexplates 168 & 153 tooth.
Example:

Does a SBC starter just bolt up to an L6?
