I'd like to run hard on occasion and was wondering if my solid lifter setup from a 273 I had lying around would be beneficial to performance. I'm no mechanic so : what would the advantage/disadvantages be ?

If your talking about swapping the cam and lifters, pushrods and rocker asembly yje 340 cam is alot better for the 340, don't swap the 273 cam into the 340 If your talking about using the rocker arms and shafts and buying a set of proper fitting pushrods for your current cam it may help a tiny bit if the motor runs okay now If your installing a bigger cam than stock then the adjustable rocker assembly from the 273 is definetly worth having Mr.Cab Racing and winning with Mopars since 1964.

I had also read somewhere that I could have the 273 rockers "upgraded" by a company in CA (sorry, don't recall the details as it's been a few years).
