Ayuh,..... Cool page, but actually misleadin',.....
The 153 is the 2.5l little sister of the 3.0l motor,.....
The 153 is
Not still in production,....
The
181 motor is still in production,..... 'n hasn't been used in cars,......
I do like that he points out these boat motors are not the Iron Duke,... which is a 2.5l Pontiac motor,......
Completely different than the 153 motor, 'n the 181 motor,.....
I'll explore the page more, later,.....
Thanks,....
