I have FM13 230"/232" .595"/.585" 114LSA cam and i want to instal it with stock heads, so i want to know 2 advance or 4 advance is better ?

How much advance was ground into the cam? I would guess it already has 4* in it for a 110icl, so I'd retard it 2* from the 4* that is in it for an ICL of 112... I bet that would work good.

last night I instal it with 4 advance, so that will be problem ? i must change it or keep it ?

Call Futural and ask for Allen - he can answer it THE best.

think hes outta town right now... away from the shop at some show... awsering machine told me he'd be back monday

No, that is not good! Install dot>dot or you might run into PTV problems on your intake valves.

I installed mine straight up dot to dot and it made *** loads of power. Now allen told me if i could have installed it on a 108icl then it would have been slightly better, but since im using a stock timing chain system i can only install it straight up.

PREDATOR-Z

If the cam has allready +4 advance on a 112 lsa , that means it is running on 108icl dot-dot.
Advancing it another 4* will run it on 104icl and definite intake PTV kissing territory (I mean piston kissing)

Kalijah98z

Ok gotcha. Allan asked me where i installed the cam and i said dot-to-dot and he also asked if i degreed the cam and i told him i was using stock timing system. Later he made the comment about i could have put it on a 108.

Thanks for making that clear Pred-Z. So i guess thats what it is on.

oOoLy

Thanks you PREDATOR-Z ... i will check with allan

Maybe you got a 112 +2 = 110 ICL and that why he was suggesting the 108 ICL which would be 112 +4

Hmm, interesting thread. A off-the-shelf Futral cam has 4* of advance I believe...so like someone said, on a 114LSA, you're sitting at a 110ICL. I dont know what the performance difference would look like if you took the cam and put it on a 108ICL.

PREDATOR-Z

Changing icl (retarding or advancing) will change valve events.
Advancing will bring the power band and power peak earlier on the rpm range. Sometimes this is done to adjust for othr parameters such as matching the powerband to the gears etc...
Some problems you might run into are piston to valve clearance, and rougher idle due to to much overlap.
