Crane H/R lifter push rod height
I am looking for the distance dimension from the roller to the push rod seat on the Crane
H/R roller lifter. Also, does anybody have this dimension for the Comp/Crower H/R lifter? Thanks in advance Karguy |

Should be one of the following. 8.800, 8.850, depending on heads and valves used.
Be Cool, Ace

Are you asking for push-rod length or the roller wheel to push rod seat dimension?
The bottom of the roller wheel to the bottom of the pushrod seat is approximately 2.350" on my new Crane HRs.

Be sure that you are getting Pontiac lifters! Many a Pontiac guys has had disastrous results of getting SBC lifters and lost the whole motor or at least serious damage was the result. They are hard to tell the difference, but the oil holes dont line up for proper oiling.
With the advent of the new racing lifters there are more serious issues. After a lifter failure three years ago, we started investigating Pontiac roller lifter limits: Crane Roller 650 lbs max Comp Roller 750 lbs max Crower Roller 900 lbs max Crower Hippo 1250 max The Hippo designation will always have an "H" in the part number. They have an oil hole drilled from the oiling annual area down to the axle thus providing lubrication for the additional pressure capability. We just ordered a set for example they are 66295H-16. These happen to be the lastest and the greatest off-set roller. These are with the bigger axle, higher tensile strength metal, and list for around $636 a set list. If that is a bit pricey the last ones were 66260H-16 (regular offset) for a little cheaper for around $500 list. A WD supplier makes about $200 on these if they sell for list, so you should get them for around $80-$100 off list. Lynn |

That said, I'm not denying that any engine buiildup should include double-checking where the oil band falls in relation to the lifter bores' oil holes.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
