| Walking on thin ice with the small cams. |

The 252 and 260 are marginal cams with that much compression. Not impossible but you'll have to be very careful on tuning your total timing and the advance rate to run pump gas. Both of these cams are all done at about 4,500 rpm. Their focus is off-idle to 3k rpm. Great for a work truck. The 268 is a bit better but still goes flat before 5k rpm. All three offer a very robust bottom end and work well in a heavy car with a numerically-low rear gear, like 3.0:1. You neglected to state what your driving intentions are for the car so it's impossible to recommend a cam. In this case, I can only tell you how a cam will likely behave. If you want a recommendation, I suggest you call a couple of the cam grinders and get their opinion.
Either of those intakes are within the performance range of the three cams so it won't matter.
With the biggest cam, the headers, and the intake combo, you should see an honest 20-40 hp depending on how good you are at the tuneup. |
