413 manifold/headers questions

[BamaCharger66]

Putting a 1965 413 (Imperial) into a 1966 Charger. The 413’s manifolds are interfering with installation. Especially the driver side where the steering box is. What are my options? Thx.

You most likely will need different manifolds. As I recall the RB block was not available in 1966. So that leaves you looking for manifolds. Other years may work but you will have to have the pipes custom bent. This has been discussed before. Try the search functions.

Get some b-body HP manifolds, problem solved.

Technically you need a drivers side b body log manifold to erase your headache.
The outlet is at the back, compared to yours between 5 +7.
Pass the same.

I believe that the 67, and the 68/9 HP manifolds will work on the driver side

'67-'70 HP/Magnum exhaust manifolds would be a good choice, but are expensive right now; $500/pr. Another option is '62- '67 383 4- barrel exhaust manifolds. They are log style and exit out the back. Maybe half the price of the Magnum pieces.

1967-1974 b-body HP manifolds will fit on both sides.

The basic shape is the same, different casting ribs and bosses. The pipe flange clocking change slightly also.

This is for reference 1974 piece
Exhaust Manifold Casting# 3751068 - LH - Date - 8-7-73 - 400 / 440 HP - B - Body - 1973-74 - USED - SHIPS FREE TO LOWER 48 - Blue Star Performance

Thx all. Had a ‘68 383 driver’s side manifold. Dropped right in.
