Banana manifold

[Robbo Blue Meanie]

Gday people I’ve just stroked my 304 to 355, the old banana manifold is a bit restrictive! What are people using for manifolds & throttle bodies? EFI
Is it worth the $$ to upgrade to plenum & throttle body?

Yes it is.

Check out this thread, the user recently upgraded to a dual plane/throttle body and was very pleased with the results.
