Begin Building Your Dream Hemi With Callies Performance Block from Mancini Racing

We’ve been slowly piecing together our dream 572 Hemi for 20 years. Our Callies iron block, crank & rods were instrumental in making it happen. You can watch our progress on our YouTube channel here.

There’s a saying that “Everybody wants a Hemi. Anybody else is lying.” And frankly, it’s a little hard not to argue. Although the legendary “elephant” 426 Hemi survived less than a decade as a production engine, it has survived as possibly the most iconic powerplant not only produced by Chrysler but all of Detroit. Seeing a vintage Mopar bearing the badge alone elevates it to top tier status. The Hemi is unequivicolly, the king of American muscle.

But with that legacy comes a hefty price tag. Original Hemi cars fetch prices ranging from “a down payment on a nice starter home” to “the gross GDP of small, eastern European nations” and anywhere in-between. And for most car guys, the idea of such a motor is far beyond their budget…or is it? You’d be surprised to learn that a Hemi’s not that far out of reach.

Mancini Racing – the headquarters for all things performance Mopar – is stocked to the rafters with all of the officially-licensed Mopar engine blocks, crankshafts and connecting rods from Callies Performance Products (as well as their far more affordable Compstar line); be it a modern G3 Hemi Hellcat 6.2L block, a 4.250″-bore G2 426 Hemi block, or a big displacement 440 Wedge block.

The price you’ll pay in repairing a worn-out original Hemi block, extracting and machining a 6.4L G3 Hemi from a wrecked Scat Pack Challenger, or haggling with some jerk on Facebook Marketplace just to find out the crank is trash just ain’t worth it anymore. Call Mancini Racing today and see about piecing together the monster Hemi you’ve been dreaming of as a kid.
