Thread: How about this cam in a 283?

Tweet

Scooter, with the springs recommended for this cam by Crane, the valves will float at 5,600. This is not a high rpm cam because his static compression ratio will not support a high rpm cam. If you want to rev the motor higher with this cam, you can install stiffer springs but the increased pressure over the nose of the lobe would probably wipe the cam out pretty quickly. Not only that, but you're out of cam in this case by 5,000. It's all about the combination Scooter. If you want more cam and more rpm's, increase the static compression ratio.

OK,I understand the reasoning so far. But lets say I am stuck with this block and pistons and want more horsepower than this setup would produce but yet keep it a streetable vehicle.What would you do? And I do believe that the biggest valve I can use is 1.94". Gears,converter,special grind cam,,,? I am trying to learn and I believe that this motor/vehicle could be a screamer if built right,,,considering the limitations of bore size and compression. Maybe I should ask it like this,,,does the late ICP really reduce compression pressure so much that the motor won't make horsepower with the bigger cam? If it creates such reversion back into the intake then is the 'only' answer a blower for such a motor? I seriously understand about half of what this means but I am trying to learn why 'bigger isn't better' when the motor is just a pump???
