Any real pros or cons?

Re: Adjustable rocker
Adjustable pushrods are less expensive, but more of a PITA to adjust. With hydraulic lifters you only have to set them once though.

Why not price out all the parts and machining you need for a basic but quality build. See if the extra expense is in the budget. At your power target I think the gain is only convenience. How often are you going to adjust the valves on a cruiser anyway?
My 354 had solids with adj pushrods. After break in and the second adjustment they stayed pretty steady.

Cool. Sounds like adjustable push rods it is.NE57 wrote:Why not price out all the parts and machining you need for a basic but quality build. See if the extra expense is in the budget.

Just seems like the price for some things are coming down.

Re: Adjustable rocker
I always wondered how often you really needed to adjust the valve lash on a solid lifter cam in a street car. I would imagine a higher valve spring rate would make adjustment cycles sooner. Does anyone know when the Chrysler 300 Series service manual recommends adjusting the rockers on those engines?NE57 wrote: My 354 had solids with adj pushrods.

Sorry for the thread jack Hemi8me.

Good question. I can't seem to find the answer in my 1956 service manual.DavidBraley wrote:I always wondered how often you really needed to adjust the valve lash on a solid lifter cam in a street car.

Re: Adjustable rocker
According to my old Chilton's book, all Chrysler 300 MECHANICAL lifter cams had the valve lash set at .015 on the intakes, .024 on the exhaust. ALL OTHERS were hydraulic lifter engines.

Does anyone know the mileage interval on the odometer before the factory recommends you adjust them on the 300 series?
