These guys that do similar stuff to a modular V8, ie port and polish heads, bullitt intakes, oversized valves maybe, high lift long duration cams, and say a Kenne Bell blower, or any good blower, could be looking at upwards of 700 rwhp though, and not spending any more much than we spent to mod up a V6, I am sorry, i don't want 600 or 700 rwhp under my hood, 300 or so is plenty for me, lol. :shock: I am not running in the Winston Cup series, or even trying to break into professional drag racing, hahaha.
