Ahhh, big block vs. small block redux. The classic controversy. There is no right answer, but here's my take. If what you want is straight line acceleration, there is no substitute for cubic inches. The big block will out pull the small block - by a fairly small margin - ONCE IT HOOKS UP. Traction is not a small issue when considering the benefit of horspower in these cars. NO ONE makes a street tire that will come close to transfering all this horsepower to the pavement. Once you get over 500hp or so, first gear pedal to the metal produces lots of smoke. Period.
Big block = more horsepower = more smoke. Big block = more weight on the front end = less weight on the rear end = even more smoke. I would say the big block will begin to gain the advantage on the small block from about 60mph on. I have outrun 514s in the 1/4 mi with my 392 stroker. How much better than 11.89et, 120.5mph is a 514 going to run? (That's my 392's best time to date on street tires) I'd be interested in hearing some real world 514 et's - anyone?? The small block's lighter weight gains some advantage in handling if you ever decide to do some twisty/turny things - drag racing seems pretty boring once you give this a try, and spf has some great events twice a year with lots of opportunity for just such fun! Noodling on a small block - changing your own spark plugs for instance - is easy and a satisfying experience with the small block. It is major surgery and just as painful with a big block. A big block gets you bragging rights, an engine compartment stuffed to the gills, a lower frequency exhaust rumble, and all the rear tires you care to buy. A small block gives you a better balanced driving machine that is easy to work on and has more power than you can use. Take your choice. The good news is, you can't go wrong!
Happy Motoring!
