that looks really good . it's making very good torque & hp . the hp hasn't even started dropping off yet @ 6200 rpm . & with stock heads i don't think you could expect much more . I'm sure there's more in it also . head work or a set of aftermarket alloy heads would make a huge difference . i like that 484 lift mopar cam as a street cam . well mate enjoy that 440 it's right on the money
. where abouts are you ???? ole morrigan is looking for somebody to do her 413 & i think the bloke that done yours did a wicked job . I'm quite surprised by that hp with stock heads , hell he can build a engine for me any time thats a really good combo .
i'm guessing it would have had larger valves & port work to make that power . but i'd like 2 see the spec's .
are you using stock rocker arms ?
& what fuel ??
