From memory the 105TC has smaller inlet ports but I think that is all.

Hi Guy,

Is there a gain to swap a 1756 Beta Head with a 105 TC Head ?

thank's.

So,

the 105 TC head look's like the abarth 125 TC on the inlet port 33/36

the 130 TC seem's to have a native larger ort 35/36

Are this difference propice to major the torque, if the 105 tc head and the 105tc piston are fit to a 2l beta bloc?

I read on the forum , that a more high velocity on gaz are propice to major the torque.

The inlet manifold may be a beta 1800 manifold coupled with a DMTR 34 91/100 .

for the AAC, I hope Guy , you can show me a propice profil for the cam for this configuration...and the objective to drive a beta 1300 gearbox with more torque, not to high speed but on tarmac regularity race ( like boucle de spa in Belgium..).

the 105 TC cam have a 9.56 high , the beta 9.4, I think using 105 TC cam I favorise the opening of the cylinder, but wath is effective for the torque ? High or duration?
