just wondering if anyone knows the stock pushrod length on an 87 305TPI is, ive looked everywhere ,thirdgen, cranecams, compcams, etc.... well i went to the local auto parts store and they didnt know but i have some specs on possible replacements;

Mfg: Cleavite- Length= 7.216" PN: Dont Know
Mfg: CraneCam- Length= 7.793" PN: 11660-16

Would either of these work?

And finally im thinking about getting Proform Roller tipped Rockers

PN: 6906c

Will they work together? The guy at the parts store was a moron and i cant seem to find any info anywhere. My Haynes doesnt even have the stock length in it.

Thanks

Jon

 

7.200 for roller cams, 7.8 for flat tappet

 

I'm not a fan of any aluminum rocker. They don't have the fatigue resistance like steel. Either route you take on rocker ratio, they can be used on the factory length pushrods. Just be sure to check the pushrod guide slot if that is what you are using to align the pushrod to the center of the valve tip. Proper clearance on the rocker stud side of the pushrod slot is what you will be looking at (increasing the rocker ratio brings the pushrod closer to the rocker stud).

 

THANKS!:hail: :hail:

There may also be a problem with the rod/main bearings so i might be forced into just replacing the whole motor. but either way thanks for the info.
