50s Hemi Engine Build With 21st Century Technology - A Contemporary Chrysler - Tech

Hot Heads offers a Street Performance harmonic balancer to replace the stock style balancer and crank hub. These are based off a late-model Mopar unit and are marked to correspond with their timing cover pointer.

Hot Heads also offers a high-rise, dual-plane 4bbl intake manifold with an rpm range from idle to 5,500. Combined with a Holley Street Avenger 570-cfm carb, this combo should provide plenty of torque on the low end. Since the 331 series heads do not have a water outlet in the front like the later 354 and 392 heads, the outlets in the front of the intake will be used, along with a remote thermostat housing.

A vintage Vertex mag will provide the spark for the Chrysler. We took ours to Don Zig Magnetos where they put 14-degrees initial advance in it to make it a little more street friendly.

Another upgrade available from Hot Heads is this vertical spin-on oil filter adapter that uses a modern oil filter to replace that messy stock canister type.

A pair of tuned, block hugging headers courtesy of Doug's Headers tuck neatly against the sides of the block, which will ease installing the Hemi in our F-1. These feature a metallic ceramic thermal barrier coating to significantly lower underhood temperatures and extend the life of the headers.

Speedway Motors provided the aluminum double upper pulley, while the lower is a Hot Heads unit that is designed to mate to their harmonic balancer. Also note the Bill's bracket that attaches to the upper water pump bolts.

Here's our accessories installed on the modified Bill's brackets from Speedway Motors. That's a Vintage Air A/C compressor on the left and a Powermaster PowerGEN alternator on the right.

With everything bolted up, our Chrysler is looking lean and mean and ready to drop into our F-1.
