fm13 cam
fm13 cam i'm getting ready to order the fm13-112 from futral and have questions?????
1. should i or is it needed to have the cam ground with some timing?? if so,how much( i will be using the stock timing gears w/ a ls2 chain).
2. what would the added timing do for me???
3. i will probably have a 100 dry shot of nitrous just in case it's needed..(there's always someone quicker)..will adding the timing be a problem for this application????
thanks all in advance

I think the futral cams come with +4 ground into them off the shelf. Advance moves the powerband down in the rpm's so that the powerband is more useable. 112+4 is the best all around power/tq combo. 112+2 is going to give the best peak hp #'s ... but doesn't have as broad a powerband.

I had a F13 112lsa +4 (108ICL). GREAT road race type cam.
BTW: Advance does NOT broaden your powerband. It simply makes it occur sooner. Widening your lsa (to a point) will broaden the powerband but will peak later compared to a narrower lsa... Most go with 112lsa to get to the power sooner on the street, not wanting to rev as high as a 114 (or higher) lsa needs.
I wish I had got my F13 with only 2 degrees advance (110icl), everything said and done....

I have the f13 112+4 and Can vouch for the power band being right where you want it. Allan will tell you that avg power is more important then peak power and recomend the 112+4 to you.
With 4 degrees advance, I still shift at 6800 for best results and power starts real early .
My car is heavy and tq starts from just above idle all the way to redline
as for nitrous, mine loves my little 75 shot although I have no track times with it yet

Be ready to wait for the cam because I ordered mine(F13 on 114) a little over a month and a half ago and still haven't got it yet.

Please don't waste a post telling me how many phone calls companies get and how it's difficult to answer each one.
