With everything else starting to move more smoothly, its time to turn my focus to the motor. Originally, the plan was to use the 4 barrel single plane CV-1 intake, modified for EFI. But after a mock up of the intake, Wilsons throttle body and Extreme 4500 hat (I borrowed one of those), the final setup sat a WHOLE bunch higher than we had anticipated. We were going to just live with it and mod the fiberglass hood.
However, a newly available universal tunnel ram is now available for the CV-1 heads. This intake has a 2X4 base with a configurable top. For a carb setup, you add a spacer to the plenum to make it the correct volume for your ci and RPM range. Then you add either a double 4150 or 4500 top depending on which style carbs youre using.
For EFI use, you add the required spacer, and a flat top. Then you modify the front of the manifold to accept a throttle body. And setup this way, its a bunch lower than the single 4 intake and all the required pieces. Pics are of a prototype 2X4 base that I borrowed to do some comparisons. I will be switching to the 2X4 base and front mounted throttle body setup. In addition to a lot less hood interference, it looks a whole lot cooler too.
