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

dust451, thanks for the links! and 70Duster, i currently have 1.04 bars in and they're great (even with the little slant not "beat you up stiff" and i've actually never heard of that trans i will definitely be looking into that and the post. And connectors are definitely first on the list! Does anybody know though what the deal is with motorhome 440's though? Yes it's a smog year motor but there's no cats on the motorhomes, has a big thermoquad with no smog stuff, probably loooow compression (from the factory) but are they any different than a passenger car motor? I believe they have extra water jackets???
