Matt, looks like a good combo and should move that Nova nicely. I Ran a 400 with a 268XE and DartII heads in a '63 Nova. With a 750 Holley and a 3" drop base air cleaner on a RPM Air Gap, everything cleared the stock hood. I'm not certain, but I believe the Vortec intakes sit a little higher than traditional small block intakes. If so, you may have hood to air cleaner interference. Good luck.

i agree. i think that is going to run VERY good, especially in a 63 deuce, if you can get the power to the ground. you need to get a convertor though, i don't think that cam is going to like the stock convertor. i'd say it would love about a 3000 stall, but that is a PITA if you drive mostly on the street. if you get it going and make some runs at the strip i would like to know what it runs, if you don't mind telling.

That's a nice combo, should work well on the street, probably shift at around 6000-6300. The block is a high nickel with the 020 casting found under the timing chain-nice. desktop dyno would give an idea what it'll produce

Very very common combo. Lots of people get good results with it. Should do over 400 HP at the crank easily if it had the right size headers. The 305-sized ones will choke it somewhat.
