Air can circulate beneath the plenum; the plenum is separated from the hot motor oil being splashed onto the bottom of the intake where it seals the lifter valley.]] |
Only because the Chevy V8 uses the intake bottom to seal the lifter valley is this called to attention. Other engine that use a separate plate to cover the lifter valley have had "air gap" intakes all along. | Only because the Chevy V8 uses the intake bottom to seal the lifter valley is this called to attention.

The Edelbrock Air-Gap intakes will require a longer warm-up. In cold weather this can lead to driveability problems, almost like a tunnel ram. The air/fuel mixture- if tuned for a fully warmed up engine- will be lean until the engine is up to temp. This can be compensated for by the choke, but if using the choke, spirited driving is out until the choke is fully open. | The Edelbrock Air-Gap intakes will require a longer warm-up.

One of the more useful adaptors (if it can be called that; Edelbrock does) is the Edelbrock p/n 2732. It is a simple flat steel plate and a pair of gaskets used to prevent vacuum leaks at the secondary side of the intake when mounting a squarebore carb onto an intake having a carb flange designed to accept ''either'' a squarebore or spreadbore carb. | One of the more useful adaptors (if it can be called that; Edelbrock does) is the Edelbrock p/n 2732.
