don’t even know if any­one ex­pected

Mopar to in­tro­duce a 1,000hp crate en­gine. Every­one I spoke to was still suf­fi­ciently shocked by the 6.2L Hell­crate and its

707 hp. Who would need more than that? Mopar thinks you do. Ig­nor­ing most of the ex­ist­ing crate-en­gine parts, Mother out­did her­self by fin­ish­ing devel­op­ment of the new Gen III–based 7.0L Hemi block, then ex­humed the Ele­phant nick­name from 1964. Then stuffed all the parts into a crate and called it the Helle­phant.

The Helle­phant is based on a re­worked alu­minum Gen III 426ci block that has ad­di­tional cast­ings in the lifter val­ley and crank­case, heavy-duty in­ter­nals, and 3.0L su­per­charger. The dyno said 1,000 hp and 950 lb-ft of torque, so be pre­pared to up­grade the trans­mis­sion and maybe the drive­shaft, dif­fer­en­tial, and brakes. The block has a 4.00-inch stroke and 4.125-inch bore, and was drag-tested in the

2018 NHRA Fac­tory Stock Show­down class be­fore be­ing mod­i­fied for the street.

There wasn’t a price when we saw it, but the prom­ise was a turnkey—or “al­most” turnkey—pack­age that in­cludes a PCM, power distri­bu­tion cen­ter, wiring har­ness, chas­sis har­ness, ac­cel­er­a­tor pedal, and all the lit­tle parts to drop it into an A-, B-, C-, or E-Body. Mopar also took care of the FEAD with an op­tion for power steer­ing.

This goes way beyond a crate en­gine with a big num­ber. The Helle­phant is de­signed to use 93-oc­tane fuel, and if you al­ready have a sturdy fuel sys­tem with an elec­tric pump and a great cool­ing sys­tem, all the dif­fi­cult parts are done. We’ve played with the crate en­gine wiring har­ness and in­stal­la­tion sys­tem in the past, and it is re­ally just a mat­ter of hav­ing a good power and ground.

Re­mem­ber this day. Now you can buy a 1,000hp, bolt-in, likely war­rantied, crate en­gine from the fac­tory and in­stall it in what­ever you like. No plumb­ing tur­bos, no mon­ster ni­trous hits or huge com­pres­sion or cu­bic inches re­quired. How long will it be be­fore we see one swapped into a Mus­tang?
