Most powerful mass production N/A V8

[marcus_667]

theres something about a the sound of a V8 that can't be beat imo.

Flat 4 (subuaru), Flat 6 (porsche), V12 (ferrari) all sound good, but theres something about the V8 i prefer.

Nom Nom Nom.

one of the best 4 cylinder engine noises is this imo specially with a T34 strapped onto it

Chevy 572 c.i.d puts out 620hp or 628.6PS

The ZZ572/620 does indeed put out 620bhp - but the ZZ572/720R version, which I was referring to and is shown in the video, is 720bhp.

We're into that horrible territory of whether we consider them mass production or not however.

Its basically a race engine, in a road car, and production is 20 per year (Source )

So i'd have to say that it doesnt count, any more than the cobra kit car with the chevy big block engine and 1350hp does, or the Pro Stock drag racers mentioned above.

Its only 20 per year because thats probably all they are geared up to produce. If they planned on building 1000 because the demand was there, then they might have been able to; therefore it would be classed as "mass" production, or if they planned to build it for the next 50 years then it would count?
