Cam suggestions for a 360

318willrun said

If you want a cam similar to a factory 340, Mopar Performance part number P4452761AE (Summit Racing). This would be the size you would be looking for. Go to comp cams, lunati, crane, and as many other brands that you wish and look at similar sized cams.
A cheap version would be Summit 6901 cam. Hope this helps.

Sorry brother. That P4452761AE cam is the recommended high performance replacement cam for the 340. Only valve lifts are similar and that's it.

OE 340 cam...... Int. / Exh. .... Lift..............overlap .... C-line
P4452782 ----- 268/276 --- .429/.444 ----- 44 ---------- 114
P4452761 ------ 268/272 --- .450/.455 ---- 50 --------- 110

While the advertised numbers look similar, the @.050 numbers show the spread and how dociles the OE cam is.

OE 340 cam ..... 208/214 @.050
4452761 cam ... 228/231 @.050
