Newbie question about rocker ratio

ozmoparjoe said

Hi everyone, i'm just chasing some info on rockers and rocker ratio's.
I have a 1968 383 and need to replace the rockers as they are worn where the shaft goes through, this is the comp cam i have for it Mutha' Thumpr 235/249 Hydraulic Flat Cam and Lifter Kit for Chrysler 383-440
Heads are factory 906, i'm just a bit confused on weather i need to buy 1.5 or 1.6 ratio rockers? Comp cams tell me factory rockers will be ok to use so will these from 440 source be ok? Rocker Arm & Shaft Assembly - New-440 Source
If not, happy to listen to suggestions of aftermarket rockers that might be a better choice. The engine will be just a mild build, nothing crazy so not looking to buy the most expensive stuff out there. Also keen on any info on push rods too.
Thanks!

If it were me I would go with adjustable rockers..For one they are true 1.5 ratio and the factory rockers are not very precise which in turn going with 1.5 adjustables will get more out of your camshaft..I've used the Harland Sharp roller rockers..Not the ones that have the needle bearings but the ones they make that are bushed..I bought mine through Mancini and they're a decent set of rockers..Once again I'll say that going with the adjustables will let you get the full potential out of your camshaft...Another issue I've seen out of stock rockers that have some wear and age on them is the tip of the pushrods pushing through the rocker arm when going to a bigger cam and stiffer springs.
