I don't know if this has been asked yet but how fast do you go with trick flow 240's ?
“Generally”, when talking about
exactly the same head, then yes.
But...... not necessarily.
Depends on where the extra cc’s come from, which may or may not result in a change to the minimum CSA(cross sectional area).
For example, if you’re working on a head where the min CSA is the pushrod pinch, and you do some porting everywhere else in the port....... but leave the pinch area untouched....... you have increased the “volume”(cc’s), but you have not increased the minimum CSA.
