I don't quite agree that 440-1's would be budget minded. The Harland rockers cost more for the 440-1, I think an EZ headed combo with the Crane R280 roller would make a great combo, or ported super Victors.
I run the ported 440-1's on my 500" low deck, I'm getting it figured out but haven't been super impressed so far compared to my old 451 E-headed combo but that car was lighter and had a big tire.
