I am not running either of those intakes, the 1st 1 is a dual plane MPFI intake, teh 2nd intake is a Scorpion or Black Scorpion single plane tunnel ram intake.

I am using a cross ram Mercrusier intake manifold, which looks exactly like teh stock Vortec 305/350 manifold except it has conventional external fuel rails and injectors.(inside the marine intake has a flat floor rather than the mess that the L31 intake has)

Here it is

In order to look at the prices of the link I just provided, you need to go over to the list on the left top of the link and select INTAKE MANIFOLD AND FUEL RAIL. Then the prices for teh intake and other parts will be displayed.

Yes these parts are VERY expensive if you buy them new from a Mercruiser dealer.

PAGE 27 OF THIS LINK TELLS YOU EXACTLY WHERE TO BUY BOTH NEW AND USED CROSS RAM INTAKE MANIFOLDS(6TH post from the top). pLUS IT DETAILS WHERE YOU CAN BUY A VER NICE INSTALL KIT WITH GM COLOUR CODED INJECTOR WIRES AND WEATHERPACK CONNECTORS FOR $275.

I did my COMPLETE marine intake conversion for $980 including PCM tuning.(slight VE table and Injector Constant tuning). This included the upper and lower plenums, 4BAR FPR, stainless steel fuel rails, 8 flow tested and cleaned EV6 injectors(design used on LS2 and LS7)(pretty much everything pictured here http://www.mercruiserparts.com/Show_... and+Fuel+Rail

I was the 1st Canadian and 2nd North American to complete this swap.(as far as we know) There was sunstantial time and energy expended in studying the feasibility of the marine intake conversion. My personal truck is far from actually needing this conversion, I did it to help out all teh guys who need more fuel for their stroker, dry nitrous and forced induction setups.

The marine intake (cross ram L31 look alike) uses the stock cruise control and throttle cables, stock MAP sensors and stock t-body, allows ANY supercharger that is designed for the 96-99 trucks to fit directly onto this intake, any air intake like Volant or K&N FIPK will fit as well. Plus this intake manifold is a GM piece designed by GM engineers.
