Quote: If you take a car with a 500 hp 360 and take it to the track it'll run a number. Now, if you take that same car, pull the 360, stuff a 500 hp 440 in it and take it back to the track (traction not being an issue), it will go faster. I had a 408" (I know that's not a 360) small block, 11.2:1 cr, 270 cfm eddie heads, torker II intake, cam was 231/237, .560 lift on a 108. Based on others' builds, I would say it was pushing 475-485 hp. The cheap POS eagle cast crank broke after 6000 miles (rated to 500 hp and 7000 rpm!!) ((my own fault, shoulda known better)) so I built a 440. Stock crank, stock rods, KB flat tops, ported 452 heads that were also in the 270 range on the intakes. Don't know what the compression is (don't care, it runs on pump 87 at 5500 ft) 228/236 cam (TQ50), less lift 110 lobe sep. Torker II intake and I dynoed this one. 485 hp, 507 tq. Everything else was the same. Truck is faster with the BB. Same 750 carb as well. 440 needs more timing, sounds pretty good, 408 had a wicked exhaust note with that compression and a little more overlap. My point being, car being the same, the 440 will start pulling harder, sooner due to the extra cubic inches, no so much because of the longer stroke, which is only .160" longer. Start changing the car to favor each specific engine and the results may be different.
You need to go back and reread my post it says 500hp each with converter and gears to match the motors rpm range. You put a 440 where you had a 408. You also said you never dynoed the 408 but did the 440 so this tells me you got everything out of the 440 being dyno tuned and the 408 was not to it's full potential. Correct me if my statement is not true.
440 would win. Longer power band, better torque and you don't need no stinking stroker crank, high stall or much gear to do it. The 440 will launch better, pull harder and et better.
