Crane 2031 Cam and pushrods/rockers

Cali95gt · Mar 30, 2011

Ok, I just got my crane 2031 cam yesterday and will be installing it next week.. I know only of people running it with 1.7 rockers.. However I have 1.6's.. Would I be ok keeping my 1.6's with stock length pushrods or do I need to get 1.7's?
also I have edelbrock 1.90 valve performer heads

Thanks

No problem , but the 2031 is designed to run with 1.7 rockers so I think that you will not see the full potential of the camshaft .

You will need to measure the pushrods with the cam installed because the 2031 has a small base circle . I'm running the 2031 with milled GT40X heads on stock pushrods in my 95 without any problems .

With what size rockers?

With pedestal 1.7 rockers.
I recomend you to buy a set of pushrod checker tool . It's a cheap tool that provides a great way to check the valvetrain geometry and find the proper pushrod lenght: http://www.summitracing.com/parts/TFS-9000/
Don't forget to degree the cam . Mine was installed like the original cam chart (without advance or retard) . It's a great street cam with a good lope and great power . You will like it !
