Cam choice

**Goldcuffs** · 11-30-2009, 05:50 PM

I know this subject has been beat to death but fuck it here it is. I CAN NOT make up my mind on what cam. I DON'T want a choppy idle but I don't know how big I can go before idle is affected. I was thinking of the 224R- 224/224 .581/.581. Is that too small or too big? Also will I notice any performance gain or do I need to go big?

The chop really comes from low LSA, so if you want no chop, go for the 114LSA 224R cam and you should be good to go.

I think it's offered in a 116 too. Do you think that would move the power band too far up?

i doubt it would be noticeable, but a 114 is gunna be pretty tame

If you are going through TSP ya go 224r with 114 LSA nice add in pwer adn idle will not be choppy either.

I myself love the lope so I am gonna go with a 112 LSA

Lope is caused by overlap which is obviously the amont of degrees both the intake and exhaust valve are open. A simple formula is take duration at .050 and:

Add the intake and exhaust durations
Divide the results by 4
Subtract the LSA
Multiply the results by 2

or

add IVO+EVC This info will be on your cam card...
