I believe that Show Cars sells an adapter to use the stock air cleaner housing on a ''modern;'' carb.I had one,remember who I sold it too,likely cis avcaileable.
I don't know,but it would be nice if they work as advertised.They're priced in line with regular lifters,.I would still usse my ''old school''break in.''methods along with a good,high zzzdp breakj in oil.
Comp Cams has recently come out with a set of lifters for the mild build engines that many of us do.They say that the DLC coating eliminated the need for ''break in''It's something worth looking into.
