did they make crossram for 340s or other cool intakes

Theres no more really wild and cool intakes being made for the small block.

You can still get a Weiand tunnel ram, INDY cylinder head makes the MOD MAN set up, MP/Edelbrock have the 6pak, but dualquads and cross rams are gone.

Perhaps you can get an offenhauser, but they are very expensive. They have dual quad intakes. Check Summit racing for them.
