Front right pad
The websites I went to are all over the place and I am so confused, can anyone tell me what engine I have and what it was from? Thanks Ron
My Prosis data base said
68-69 5.4 litre (327 I presume)
78-79 5.7 litre 350
as for four bolt, the only method I know for sure is,take off pan or try to look at main caps with front cover removed.
I also thought years ago that a block casting number ending in (010) was a four bolt, bought one from junk yard, paid 4-bolt price, a few years later I decided to use it , tore it down and it WAS NOT a four bolt. Lesson learned the hard way.
