Big valves, small bores, and a lot of boost....

Well that is the combo that both me and a friend are doing

he has a 4.030 bore and a 2.1" intake valve and i have the same bore but with a 2.08 intake valve

Both of us have the valve shrouding on our minds. We both are aware that there could be some potential problems but we are not sure of what. We figured since this wasn't an N/A application and a lot of boost was involved, that it wouldn't make as extreme of an impact but i'm sure

Anyone shed some light?

up

I run 2.10" intake valves on my 396 (.030 over)....no shrouding problems.

I am, too. 2.10/1.65 Manley Ti valves in 215cc RR AFRs on my NA 396...

Jason, just how did you determine that?

I'll be back

What size chambers are your heads? Big valves in a small chamber will shroud regardless of bore.
