Default Cam Design 88/95 versus 96

I've been looking around at packages and cam recommendations for TC88 bored to 95 versus TC96 engines. Almost invariably they are the same.

Seems to me that the short rod long stroke tc96 [less tdc and bdc dwell and quicker piston acceleration] would benefit from new cam desgins.

Is this just not critical or have cam grinders just said good enough is good enough?

There was a similar question posted on the HQ tech sight today.

If it was you, you know you got a good answer, if not let me know and Ill give you my 2 cents!

Thanks and yes that was me and I did get a good answer. I thought the 96 rods were quite a lot shorter [versus 88 rods]than .009 in. I was thinking about .100 shorter rods and of course a much longer stroke.

mentor,Which cams are you using and are you using gear drives or chain?I willbe using HQ 575s but did not know if the chain drive would be adequate ornot with that much lift and spring pressure. I asked Doug and he said he leaves that up to the customer but he did say when asked if it were his bike what would he do and he said probably gear drive.I want gear drives but money is getting short. Thanks, Joe

For 06 (except 06 Dyna)& older motors, that is absolutely correct. I have talked with Doug about a number of builds and watch the techline regularly. The new style roller chain setup is perfectly fine in the 07 & later bikes.

The new style roller chain will handle most any cam, and the tensioner set-up is entirely different and should eliminate the tensioner shoe failure of previous years. Unless an all out race motor, the chains should be fine, am running chains with a .650 lift Woods cam with no problems in 10k miles so far.
