440 HP Estimate

C'mon now Demon... No 440, including the vaunted '67 HP with closed chamber heads actually WAS close to advertised static compression when measured..and mid 70s are advertised as 8.5:1. If he's lucky, that engine will be 8:1 when calculated, after having a valve job. Plus, it's a ring and bearing job. Not a bad thing, but certainly not a huge power producer when compared to a real modern performance rebuild. Add to that a cam that is decent for the money, but in no way can it approach 500hp in an engine built around it, much less this plan. Stock 440s (non HPs are rated at 350hp in gross terms) will sometimes exceed the factory rating, I'll agree with that, but I'd also say the dyno has a lot to do with that record. That and most of the stock engines by now have been rebuilt. Better machine equipment and better parts have been used, and more attention paid to assembly. You cant really compare different dynos as apples to apples either. Do I think it will make decent power? hell yeah. Will it break 400? Very possible, but more possible it doesnt. Not every "500 hp engine" is one. Just dont profess that at the cruise nights where everyone is liable to get upset. As far as ETs go, if it can hook, I'll toss out 12.30s at 108 or so with a tight street convertor and slicks. That only takes 390hp at the crank in a 3300 lbs car. Lots of room to improve, but also a very fun budget combo.
