I agree. With a a 340 core and three grand you'd get that thing running real good. may even have money left. This is assuming you have everything from intake to exhaust manifolds which are high flowing. But yes the scenario is biased and one way leaning, but look at what we've learned here...:) ( no I'm not scrapping my 340s to build a 5.2 Magnum, but if I were so inclined that's what I'd do because of the magnum heads.)
