CHESTNUTXE 7,310 Posted August 22, 2018 does the alloy timing cover have anything to do with what chain you use ,eg,early cover fits double roller chain ? or doesnt really matter. Share this post Link to post Share on other sites

CHESTNUTXE 7,310 Posted August 24, 2018 hey i have heard that you can put new roller lifters on an old cam ,because they are not turning is this correct ? Share this post Link to post Share on other sites
Thom 6,650 Posted August 25, 2018 hey i have heard that you can put new roller lifters on an old cam ,because they are not turning is this correct ?You can provided the cam has no scoring pitting or any of the hardness flaking off, same goes for the lifters, they can even be used with aftermarket cams (providing they are still in serviceable condition), while the factory cam is ok in the roller engines there a many better/ more modern grinds available 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,310 Posted August 25, 2018 thom can you use link bar roller lifters instead of using the dog bone and spider or its no benifit ? Share this post Link to post Share on other sites
Thom 6,650 Posted August 25, 2018 thom can you use link bar roller lifters instead of using the dog bone and spider or its no benifit ? No real need the spider setup is pretty decent and quieter than the link bars, the link bars were mainly developed as a way retrofit roller cams into non roller engines Share this post Link to post Share on other sites

Slight lope at idle, 220@ 0.050", 110 lobe sep. Probably not far off what you have in your crossy Chestnut.

It’s hard so see but that lower part above the roller could be overheated?? What do the lifter bores look like? 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
