61cc

My 347 has 63cc chamber heads giving me a comp of 10.2.
If I was to change to AFR185'S with a 61cc chamber, what would my comp be?
Would I notice the difference in performance in going to afr's?

Re: 61cc

Go for the 57cc versions. That's what i have got, and my decks are also cut. My comp is 11.1 and runs on pump unleaded with no problems.

I changed mine. I used springs that matched my cam, but incidently, they were very similar to the ones i took out.

Anyone want a set?
