77 motorhome 440 vs 71 360-what to use???

And if you apply the same all aluminum stuff to that 360, that 440 will still out weigh the 360. For the cost to rebuild the 360 vs making it a 408 vs the 440. Your best bet would still be the 408. Tons of torque and horsepower for less cost then to do the 440 up right and buy all the required Big block parts to fit it in the a body. If you look up user ou82 he just built and sent a 408 (or was it a 416?) to NY that was making like 500+ HP and 450+ TQ. Just something to think about.

True, but the question isn't whether a 440 with aluminum parts weights less than a 360 with the same parts, so that's not the point I was trying to make. Just that a 440 shouldn't make handling any worse than a stock 360/340/318 A-body if set up properly.

Now we're starting to talk about different things. I am talking about how a 440 in an A-body wont cost as much or handle as bad as being implied. Not about how someone made a 500+ 408(or 416). Thats not following the question asked in the original post. But FYI, I'm sure I could throw just as much into a 440 stroker and make 600+. If that is what dusterdan wants to know.

So far during my 440 build I have only found the headers to be the only part that has a noticeable price difference vs. its SB counter part and they are quite a bit more. Intake, heads, cams, pistons all seem to be very close in price. I havn't spent more than $20 more for a BB part over the cost of the SB part.
