I've got a '65 heavy duty shorty panel with the 240. Does anyone know of any upgraded intake manifold/carb setups that fit in the doghouse without modification? Or is the stock manifold the best working for the tight clearance?

 

So it looks like perhaps an Edelbrock Streetmaster would be the ticket.

I'm possibly looking at doing a custom setup, possibly ITB. Does anybody know the dimensions of the intake ports on the 240ci head? looking at square area and translate into a circular throttle body size appropriate...
