Hagerty recently spent months slaving over a derelict Chrysler FirePower 331 HEMI V8. We featured a time lapse video of the rebuild and now the classic car insurance company has gotten around to sticking their FirePower V8 on the dyno.
Unfortunately, the vide doesn’t show how much power the 331 HEMI is producing, but in certain applications the FirePower made over 300 horsepower. Hagerty spared no expense in their rebuild and the technicians at hand clearly knew what they were doing, so it’s reasonable to assume that this engine is producing at least 400 horsepower.
Check out the video above to hear that sweet HEMI rumble.
