Dyno a 7.5:1 400? Sure, why not?

Well as we can see, a low compression engine can make good power. This is not new news. Back in the 70s when Detroit dropped the compression across the board it did not take long for people to discover that it was not the end of the world as far as making power and getting their car to run quick. The thing about compression is that even though it does not make a dramatic difference in power by itself, it has a big effect on the attitude of the engine. I've said this before and I'll say it again. Take two identical cars, one with 8.5 to 1 and one with 10.5 to 1 being the only difference and drive both of them. Without a doubt the 10.5 to one car will be a lot more fun to drive and will sound better also. Better throttle responce and more immediate torque also. Drag race the two cars against each other and the high compression car will probly win but only by a small margin. Now take the two c ars and start going up on the cams, identical in both and tbe high compession engine will start to shine brighter. Just an opinion.
