Planning for 408 - Possible Solid Flat Tappet cams

Custom cam does not automatically give you the better result. Somebody who really knows his stuff has to decide the timing events.

I´ve tested 3 different cams so far in my 408, no solid flat tappets but hydraulic rollers from 110 to 113 LSA, one was a custom cam. No dyno but strip results....and i´m convinced now that there´s some gain with more overlap due to tighter LSA, will get another custom grind to prove my theory. Of course i could be wrong ;-)

My opinion: the mentioned hughes or howards would be a strong runner (especially autocross), don´t think there´s much benefit from split duration since the TF´s exhaust ports are pretty good. For drag only the duration could be increased of course.
