Fits: ’62 – ’72 B body, ’70 – 74 E body, ’66 – 73 C body

Important technical information to consider:

1. This Hemi kit will work for both Small block and big block B, C and E body cars because they have the same K-member.
2. Slant 6 models still require a K-member change to the V89 style.
3. Factory Hemi exhaust manifolds work perfectly with this swap. Hemi headers, in the B&E-body, work as well as they would with an original Hemi car. (This mounting system won’t create header fitting problems nor solve any.) A TT1 Hemi header is strongly recommended for the best fit and performance. In the C-body, the torsion bars are closer together and the engine offset is more pronounced than in the B or E-body — this may cause interference with headers. Factory manifolds for C-body swaps are recommended.
4. Aluminum heads — Due to reworked port locations, aluminum heads may cause header fitting problems, although not necessarily in all cases. This might have to be determined on a trial and error basis.
5. The oil pan that comes with Mopar Performance crate engines works fine, as do most pans that are specifically designed for B and E-bodies. B and E body oil pans will work in the C body.
6. Power brake boosters are smaller on original Hemi cars to allow for valve cover clearance. If your booster is larger than 10” in diameter you will need the smaller booster.
7. The kit will not work with oil pumps that have external lines that are routed toward the back or firewall.
8. Hemi cranks have 8 bolt flanges instead of 6. In most applications, if you are reusing your transmission, you must change your flex plate or flywheel.
9. Torsion bar — Due to the extra weight, a change to the Hemi style is recommended.
10. This kit works with manual and power steering, 4 speed or automatic, and cars with A/C.
11. Radiator compatibility — Choosing one with its outlet and inlet on the same side as the mating connections on the engine makes for a simpler and cleaner installation. Consider using a B/RB model. For more efficient cooling we recommend a shroud and the MP Viscous Fan package.
12. An MP high flow motor home thermostat is recommended. They come in 160/180 and 195 styles.
13. Due to the difference in location of the coil and distributor between the A engine and the B/RB or Hemi engine models, in any A engine to B/RB or Hemi swap your wiring will have to be lengthened. Upgrading to the MP electronic ignition system, if you haven’t already done so.
14. In most cases, drive shaft fabrication will be necessary if the rear axle assembly style and/or the transmission model are changed, e.g., going from the 904 to 727 transmission will require shortening the drive shaft as well as a different yoke or using a conversion U-joint.
