if you go to newman and ask them to spend there time speccin you cam for your engine,turbo spec your answer will be no if you design your own cam shape lobes wise and stuff they will machine it to your size which makes it custom
so to answer the overall question do newman do custom cams?yes
do they spec cams?no
youlll need to do the hard work theyll do machinin
alan at AVA has spent many years experimentin with different ideas
he never went to newman and asked them to spec a cam for this spec engine
he gave them the dimensions he was want not the engine spec its goin in
so we'll just say an AVA specced newman cam
that will keep us all happy
by the way ava will not sell you a cam either they will however build you a engine thats reliable and virtually bullet proof,maybe even with a ava specced newman custom cam in it aswell
