less i am blind i do not see head numbers cam size . if a bone stock 454 bottom end ? if your going by block numbers that will not say what has been done to it . i built many 496 /489 out of stock blocks and built 454 in to 427s has well has 510s so its really hard to say what can be done or is done ??less you know for sure it.s a bone stock 78 454 in that case there not much more you can do to it . if you can tell me head numbers i could tell you if the heads can make any power . your only going to go so far with a recamed 454 but if sealed up good with the right cam intake headers it should be 400 hp easy. if you want more PM me i build machine and sell bbc from 427to 638 or check out mccarthy performance. com

Took the car out for a test ride today,I don't need to change a thing it has more power than any car I have owned even my 2008 Corvette. Wish there was some way of finding out what's in it without taking it apart. Blew the tires off if it in all three gears 29x15.5x15 mickies. Thanks for everyone's advice
