There's two Dayco timing belts listed for the 944 from Summit Racing and they list length and tooth pitch for each and since I can't find that info ...which one should really fit my 87 944 NA? Where can I find the specs that apply to the timing belt for this particular car?
Summit parts nos.
95107 Pitch Length in Inches 43.88 Top Width in Inches 0.75 Number of Teeth 117 Interference Engine Yes

and 95152 Pitch Length in Inches 44.36 Top Width in Inches 0.98 Number of Teeth 110 Interference Engine Yes.

Which is right?

You need the 95107 unless you have an 944S, the 95152 is for the DOHC S and S2 engine. Why are you using a Dayco belt when Conti and Gates both make a good belt and have a long history on these engines? I've never heard of anyone using a Dayco belt; not that they don't work or aren't a good product but they sure don't seem to used by any shops or DIY'ers I know of.

All three are OEM suppliers for belts for the industry; I wouldn't worry about any of them.

They're drop shipping it to you, and they'll get their $9.95 "handling" fee. I'd just drop by your FLAPS.

I've researchd many threads regarding the timing belt issue before jumping into this rather popular matter so I do the right thing. In many of the threads the Conti lable was recommended to be "AVOIDED" because of short life history and to go with Gates or Dayco. One supplier offers an OEM belt that's made in the UK but won't specify the mfr. What is "FLAPS"?
