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

dusterdan said
Hey guys....so here's some background on what i have, what i'd like to have and i'm all ears for any opinions and comments on the matter:)

I have a 70' duster, factory slant six car and also have 2 engines here, both complete NEVER torn apart.
(1)71' 360 with 727A
(2)77 440 with 727 from a Coachmen motorhome

In the long run, i want my car to handle relatively well (keep up with base model challengers at least) and be comfortable on the highway and have a minimum of 400hp naturally aspirated. Since i'm starting from scratch either way since EVERYTHING in the drive line will have to be replaced, i just wanted some general feedback on what you guys would do??? It just seems so much cheaper to build a big block with good power than a small block with equivalent numbers and now that Procomp has aluminum heads for BB's for $450, i could shed some weight and not break the bank. My budget is about $3500-$4000 for either motor, 727 auto for either, 3.91 gears....keep in mind both are complete. Perhaps somebody can shed light as to some PROS AND CONS OF A MOTORHOME BB AS I KNOW NOTHING ABOUT THEM. Thanks in advance, you guys are great! -Dan

If 400hp is all your after then get the 360, If you want the torque then get the 440, But just keep in mind either one will need the compression brought up "at least" a solid 1.1/2 points, you can make the 440 handle well even with iron heads, The Procomps i'd stay away from, get the steaths, If you play your cards right & shop "smart" along with a good machine shop that won't rip you off you can get the whole engine done for around 3000.00 carb too pan, Start with the block & consintrate on the "shortblock" only for starters, then pick the heads/cam/intake/carb for the intended use. Shoot for a good quench, you can use the factory cranks, there both cast but plenty strong. Heres a few options.

Now you can opt. for a stroker kit like this one. This would be the kit i would get, its balanced with forged pistons.
