Someone asked me for info (engine specs) on a destroke
426 Hemi that was available. This was news to me, so I
decided to do some research to see what I could dig up.
So far...
I'm told that 396 and 400 ci versions of the 426 Hemi were
run in Pro Stock from 1972 and up. The 396 with a 3.48"
stroke and 400 with a 3.50" stroke.
Does anyone else have any more information? Post it up
and shoot me a PM or email with the details so I can share.
Thanks!

The original request mentioned maybe a 366 ci Hemi.
Sounds like the 366 ci motor might have come from a
383 destroked and topped with Hemi heads. Not sure
how many people actually ran these small Hemis, but
they sure do sound interesting!

They were used earlier than that. Ronnie Sox ran a destroked 404 cu. in. HEMI in his 1970 'Cuda Pro Stocker for a while in 1970. But generally speaking, the destroked 426 HEMI's were more common in the 1972-on up years as they made better HP/cu.in. than a standard size HEMI. Also, it enabled their cars to run approximately 210 lbs. lighter which translated to quicker acceleration out of the hole--a must when unfairly burdened with 7.25 lbs./cu.in. weight break versus the favored small block Vegas' 6.5 lbs./cu.in. and Pinto's 6.75 lbs.(?)/cu. in. breaks, etc.
