EFI Intake manifold

The manifold that comes with the Holley EFI kit is massive! It reminds me of a Edelbrock Victor. Sure looks like it will provide a substantial improvement in airflow compared to the Torker II. However, the massive height does create problems with hood clearance, even with the L-88 hood.

A L-88 hood is  right at 2" taller than the regular big-block hood. The Torker II + Carb setup comes in at 7". The EFI measures 9 1/8".

It may have been possible to squeeze the EFI under the hood, but I would have had problems getting the cold-air induction functional. After contemplating for a while I decided to cut 0.6" off the intake.

Notice how tall the throttle body pad is. Shouldn't be a problem taking a little over 1/2" off the top.

The IAT sensor sits in the pad and will have to be relocated.

Here is the manifold after cutting. The throttle body came with a 1/8" thick steel plate that was epoxied to the pad to make for a good seal. The throttle body mounting holes were made deeper and re-tapped.

IAT sensor relocated to the side of the manifold.

Here are the added vacuum ports. One 1/4 NPT for headlights and wiper door, and a 3/8" NPT for the power brake booster.
