Plenum Volume

I did think of that. But, IMO, I think it's more trouble than it's worth. It seems to run into the low 10's high 9's in A bodies. Good enough for me.

Yes yes yes, back to the tunnel ram.
I have one of those awaiting better days to come!
I remember waxing a couple of tunnel ram hemi`s back in the day w/ a rat roaster, talk about volume !
