comp 1630-16 1.7 ford spec ?

Post  torino501 on December 27th 2015, 10:35 am

whats the deal with these rockers...? there a 1.7 and not 1.73 but they are ford spec not chevy. any pros and cons as far as geometry goes? I know a lot can be corrected with the proper length push rods and such. not much loss in valve lift I assume.

They are based upon Chevrolet rocker bodies however, the stud hole in the trunions have been offset drilled so, they are not in the center of the point of trunion rotation making the rocker itself sit farther away from the spring and valve like some shaft rockers do.

what type of build would somebody use these rockers...? I guess ive got a lead on some new ones very cheap. and id guess id build the valve train around it..(push rods). but if the geometry is way off hell I don't want them either...
