I plan to bush the lifter bores in my 2 tall decks, I know some sized them to Chrysler roller lifters.
What is common these days?

In my 540 BBC it has Isky EZX .904 lifters and your push rods will depend on your deck height and if your heads have been cut. You will need a push rod length checker to determine what length you'll need.

I'm going to use Comp .904" lifters in my dart big m block but I'm having trouble finding the lifter bushings I have tried to contact CHE to get their bushings same as used in the chevyhiperformance magazine but they don't answer... Where are you guys getting the bushings? I'll probably make my own but it takes alot off time and is not that cheap...

Dang you were rght! :D they answered and if we can get a reasonable shipping prize I'll take them from there.
We machine alot of the .904 lifter bores in both SBC and BBC and rarely do we install bushings when going to the larger lifter bores.

Hey Carl,
I'm thinking about trading some sm/blk stuff for a 4.625 bore Donovan T'deck Chevy Alum blk. there are some issues with the lifter bores, having never been bushed. I can do this procedure, the question is would you go to bronze or cast iron on this Alum blk? and can i go to the .904's or just bush them back to .842's.
It would be an alcohol injected motor.

If you are going to the .904 just machine lifter bores out to the proper size as we have to blower engines that are using Jesel .904 roller lifters and we run 1250 over the nose and 460 at the seat and no issues and no bushings.
The only time we bush lifter bores is when a rule requires stock size lifter bores but the customer wants the lifter bores blue printed.
