HELP me out Mopar Fans !!! (CAM question here)
Well, With such a small engine I would use a mopar .528 284 cam as this will give you the added power and it's a mechanical cam. This cam will work well with the small heads and the lower compression, it will also give you the rump that your looking for. Little engines are vary easy to over cam so don't get greedy with it (the cam), also it has a very small overlap so the cylinder pressure will stay up and this is a must with small engines like the 273. This cam works well in the 318 also as it has a 112 intake and exhaust centerline. You will need a small converter or a straight shift though for this cam, a 2800 stall would work fine along with a 3.55 gear. Just my thoughts and what I would do.
