SBC Edelbrock Performer intake to Victor Jr intake upgrade

Originally this 406ci SBC came with a 650 Holley and a Edelbrock Performer dual plane intake.  Pretty restrictive if you ask me.  I ended up installing a Holley 830 and it was time for the intake to be replaced.  Here’s a few pics of that process.

 

Initially, the dual plane intake just looks ugly because its dirty.  Performance wise, a 406 will make a little more HP with a single plane intake.  I cleaned up and painted the Victor Jr a high-temp silver.

After removing the distributor, alternator bracket, carb and various things that were in the way…time to remove the old intake gasket and seals.  To keep trash out of the valley I just used some shop rags and vacuumed out whatever slipped past the shop rag.

After installing the intake gaskets which are being held in place with a small dab of blue sealant, its time to seal the front and rear where the intake will rest.  Dont want any oil leaks.   Oh..and the 2 cork gaskets you get with your gasket set, throw them away.  On all 4 corners where the head meets the block, make sure you get sealant there also.  I’ve seen a simple job like this turn messy because of a pinhole leak in those areas.

These two..just go ahead and throw them away.

Carefully line up the intake and place it on the engine.  This pic shows my distributor installed.  Didnt take a pic of the intake being installed.   Torque specs are 25# and pattern in the next image and in addition to this I used a little bit of thread sealer on the ARP bolts to make sure we dont have anything leaking past the bolts.
